By the way, Atheism has no moral code and without a higher power to give man a moral code to live by, we are just animals subject to Natural Selection and Survival of the Fittest, i.e., killing other humans is not immoral. At best an Atheist can subscribe to Moral Relativism, which essentially can be used to justify the Holocaust and the genocides of Atheist dictators like Stalin, Mao, and Pol Pot.

Christianity, on the other hand, commands its followers not to murder other humans.

Humans are humans and are capable of great acts of kindness and sacrifice but are prone to hatred and violence. As Christianity teaches humans are flawed beings who are sinners, therefore they can aspire to be like Jesus Christ (the "Ideal Christian") but they will always fall short. Jesus Christ taught peace, love, and forgiveness.

The problem is the dishonesty about what Christianity teaches. Jesus Christ did not teach or practice violence, child abuse, pedophilia, rape, intolerance, slavery, Antisemitism, misogyny, hate, or violence.

By only looking at the actions of professed followers, one is subscribing to the fallacy that the actions of professed followers are automatically consistent and therefore are representative of the beliefs they profess to follow. They are in fact hypocrites because they are doing the OPPOSITE of what Jesus Christ taught and did.

You are simultaneously employing a fallacious argument to claim Christianity is bad while accusing others of a fallacious argument who say Atheism is bad because of Stalin, Mao, and Pol Pot. Classic Hypocrisy.

Max Erwin von Scheubner-Richter http://en.wikipedia.org/wiki/Max_Erwin_von_Scheub...

Excerpt:
During the First World War, he served in Ottoman Turkey as the German vice consul of Erzerum. In addition to holding that post, Scheubner-Richter documented the Turkish massacres of Armenians as part of the Armenian Genocide.
...
At the end of September 1923, Scheubner-Richter provided Hitler with a lengthy plan for revolution, writing: "The national revolution must not precede the seizure of political power; the seizure of the state's police power constitutes the promise for the national revolution" and "to lay hands on the state police power in a way that is at least outwardly legal".[3]

During the Beer Hall Putsch, walking arm-in-arm with Hitler, he was shot in the lungs and died instantly as Hitler and others marched toward armed guards on 9 November 1923.[4] He had brought Hitler down and dislocated Hitler's right shoulder when he fell. He was the only first-tier Nazi leader to die during the Putsch. Of all the early party members who died in the Putsch, Adolf Hitler had claimed Scheubner-Richter to be the only "irreplaceable loss".[5] The first part of Hitler's book Mein Kampf is dedicated to Scheubner-Richter and the other fifteen men who died in the Putsch.

Hitler and Jihad http://archive.frontpagemag.com/readArticle.aspx?...

Excerpt:
Perhaps the earliest recorded evidence of Hitler’s serious interest in the jihad was provided by Muhammad ‘Inayat Allah Khan [who adopted the pen name “al-Mashriqi”—“the Orientalist” or “the Sage of the East”]. Born in the Punjab in 1888, al-Mashriqi was a Muslim polymath who attended Cambridge on a government scholarship, and excelled in the study of oriental languages, mathematics, engineering, and the sciences.

Not only did Mashriqi translate the standard abridged version of Mein Kampf (then commonly available) from English into Urdu, during one of his sojourns in Europe, which included time spent in Berlin, he met Hitler in the early years of the Fuehrer’s leadership of the National Socialist [Nazi] Party. Their meeting took place in 1926 at the National Library. Here is the gist of Mashriqi’s report on his interaction with Hitler as described in a letter to the renowned scholar of Indian Islam, J.M.S. Baljon:

I was astounded when he [Hitler] told me that he knew about my Tazkirah. The news flabbergasted me. . . I found him very congenial and piercing. He discussed Islamic Jihad with me in details. In 1930 I sent him my Isharat concerning the Khaksar movement with a picture of a spade-bearer Khaksar at the end of that book. In 1933 he started his Spade Movement.

Mashriqi also wrote this independent summary of his 1926 encounter with Hitler on May 31, 1935:

Heinrich Himmler's Adoration of Islam http://archive.frontpagemag.com/readArticle.aspx?...
Excerpt:
Less well known is the fact that the same Heinrich Himmler warmly embraced Islam or "Mohammedanism" as it was called then. He admired the religion of the Muslims because it promised that there will be "beautiful women in paradise for those who die in battle." (Many of today's suicide bombers – often sexually frustrated young males – have also deluded themselves into believing that 72 smiling "Huris" or virgin beauties are waiting for them in paradise.)

Felix Kersten (1898-1990) was Himmler's personal masseur and confidant. It was seven years after the war that Kersten published his sensational memoirs, "Totenkopf und Treue." The Kersten memoirs were also published in English but, unfortunately, the original chapter on Himmler's "Enthousiasm for Islam" ("Begeisterung für Islam") was conspicuously lacking in the English edition. Although some of Kersten's claims are exaggerated, other parts of his memoirs seem to be fairly reliable. Roger Manvell and Heinrich Fraenkel, two leading Himmler biographers, believe that Kersten "became the most powerful influence in Himmler's life after the death of Heydrich."

‎"When the Mohammedans attempted to penetrate beyond France and into Central Europe during the eight century when they were driven back at battle of Tours. Had the Arabs won this battle, the world would be Mohammedan today. For theirs was a religion that believed in spreading the faith by sword and subjugating all nations to that faith. The Germanic people would have become heirs to that religion. Such a creed was perfectly suited to the Germanic temperament."
~Adolf Hitler quoted by Albert Speer, Inside the Third Reich, page 96.

"Had Charles Martel not been victorious at Poitiers, already, you see, the world had already fallen into the hands of the Jews, so gutless a thing Christianity! then we should in all probability have been converted to Mohammedanism, that cult which glorifies the heroism and which opens up the seventh Heaven to the bold warrior alone. Then the Germanic races would have conquered the world. Christianity alone prevented them from doing so."
~Adolf Hitler, August 28, 1942, midday from Hitler's Secret Conversations, page 542)

"You see, it's been our misfortune to have the wrong religion...The Mohammedan religion too would have been more compatible to us than Christianity. Why did it have to be Christianity with its meekness and flabbiness?"
~Adolf Hitler - August 28, 1942

"The Nazi Master Plan: The Persecution of the Christian Churches"
July 6, 1945
http://www.geocities.ws/nazis_persecuted_churches... http://www.geocities.ws/nazis_persecuted_churches... http://www.geocities.ws/nazis_persecuted_churches... http://www.geocities.ws/nazis_persecuted_churches...

In Christianity one is saved by faith, NOT by works. Faith is what is in one's heart and soul, that generally manifests itself in moral behavior. The only unforgivable sin is the rejection of God.

This is the New Covenant of which Jesus Christ brought to mankind and which was prophesied in the Old Testament.

Further, Christianity teaches "Free Will” and Faith canNOT be forced upon the individual. Humans can only affect other humans' actions. Humans cannot force someone to have "Faith" in God.

God granted man "Free Will", which means it is God's will that the individual be allowed to choose to accept God and his teachings or reject God and his teachings and therefore, it is a violation of God's will for another man to attempt to impose "acceptance" upon the individual.

The Classical Liberal idea of Life, Liberty and Property is based on the Christian concept of "Free Will". The Founders of the US incorporated this idea into the Declaration of Independence, i.e., all men are endowed by their Creator with the unalienable right to Life, Liberty and the Pursuit of Happiness [Property].

Furthermore, the separation of church from state finds its origin in Christianity.

Jesus Christ said "my kingdom is not of this earth" and "give unto Caesar the things that are Caesar’s and unto God the things that are God's".

Many of the US Founders were Christians.

As to the "Christian" Crusades:

The first "Christian" Crusade ("Christian" is in quotes because the concept of Holy War is found nowhere in the teachings of Jesus Christ - it was borrowed from Islam, essentially "Jihad") began in ~1095 AD and was primarily defensive in nature, i.e., the goal was to recapture lost Christian lands that had fallen to Islam, e.g., Anatolia (Turkey), the Holy Land, and Egypt were all once part of the Christian Byzantine Empire. Constantinople (now Istanbul) was once the seat of Eastern Christiandom.

The first Muslim Crusade began in ~630 AD and was initiated by Mohammad himself. The Muslim Crusades were offensive in nature, i.e., the goal was to conquer non-Muslim lands and convert or subjugate it's inhabitants to Islam or kill them.

So, it took Christiandom (the West) over 400 years before it responded to continued and relentless attacks by the Islamic Crusades.

Furthermore, Muslims following the example of Mohammad (Islam) have been responsible for slaughtering over 270 Million non-Muslims in many Genocides during its 1400 year history.

120 million Black Africans
60 million Christians
80 million Hindus
10 million Buddhists

For example, after the Muslim conquest of India, the Bahmani sultans in central India made it a policy to kill 100,000 Hindus per year. In 1399, Teimur slaughtered 100,000 Hindus in a single day. Even Sufi saints are on record of condoning the subjugation of Hindus through force.

Besides ISIS, this slaughter is still occurring in places like Darfur, Nubia, South Sudan, Nigeria, among many other areas of the world. I suggest you study the plight of the Coptic Christians (original Egyptians before the Arabs invaded) in Egypt.
