Check the case of Yaser Esam Hamdi - born in the US of Saudi parents (which makes him a citizen); captured in Afghanistan and declared an "enemy combatant"; and released to Saudi Arabia in 2004 on condition that he renounce his citizenship.
There is considerable opinion that his renunciation was invalid because it was coerced
I think they don't lose their citizenship (which is a guarantee of the Constitution), but rather lose their "privilege" to vote (which is an issue of state law). Most states restore voting privileges after completion of sentence (including terms of parole or probation). Alabama, Florida, Mississippi, and Virginia are among those that do not and which require special government action to restore the individual's privilege, even after the sentence has been completed.
History suggests that these laws were enacted after Reconstruction specifically to disenfranchise freed blacks, and certainly there's a disparate effect on racial minorities. Yet the SCOTUS upheld it in Richardson v. Ramirez.
Time to revisit that decision, perhaps.
or for instance Nazi war criminals who lied to obtain citizenship but have since been exposed and had their naturalization revoked. But no other country will take them and so they remain in the US, stateless.
actually, I'm pretty sure they don't - "natural born" citizens of the US cannot lose their citizenship, unless they specifically revoke and renounce it, and pay the associated fee. See eg Afroyim v. Rusk, Kennedy v. Mendoza-Martinez, or indeed the 14th amendment to the Constitution.
(There is a distinction between those who have citizenship through birth and those who acquire it through naturalization - since the citizenship of the latter depends on Congress rather than on Constituitional law)
But you're probably talking about "moral" or "ethical" rights rather than "legal", yes?
"People do not have to use the words ‘Jew up’ or ‘Jew down’ – as some American state politicians have done of late – to give rise or feed into unfavourable, hoary old perceptions of Jewish businessman and their practices."
sources please? I would like to know at whom I should direct my ire.
oh, give it a rest. You and Eli blithely ignore the real issue - that this pompous ass celebrates academic freedom in China and Iran, but boycotts Israel as a matter of principle. By ignoring this inconvenient fact in favour of emphasizing these silly accusations, you hope to lend a veneer or respectability to what is a disgusting act of gross dishonesty.
Whether he hates Jews or loves Jews or is indifferent, it don't matter in the least. What matters is that he sacrifices honesty in favour of fashion.
