People have probably heard that Abdul Rahman is facing the death penalty in Afghanistan for "apostasy", having converted to Christianity about 15 years ago (I've heard both 14 and 16 so am splitting the difference.) Rahman converted while working with a Christian aid group in Pakistan. He lived mostly in Germany until 4 years ago, when he returned to Afghanistan following the overthrow of the Taliban government.
In January 2004, Bush praised Afghanistan for their constitution which "talks about freedom of religion", although at the time the US Commission on Religious Liberty warned that the constitution explicitly instated Islam as a state religion and barred religious freedom. More recently, just a few weeks ago Bush praised "liberated" Afghanistan as a Muslim country that respects religious freedom. (He also, incidentally, praised Afghanistan for its progress on women's rights, despite the fact that women continue to be imprisoned for having been raped, that rape is only a crime for the woman and that Bush has never met a women's right he did not oppose.)
So maybe this explains why Christians are so silent. Bush, to be sure, has expressed "concern" but no more. Where are Jerry Falwell? Pat Robertson? Bill Donohue? Bill O'Falafel? Pat Dobson?
They are so ready to scream about a "war on Christmas" when a store clerk says "happy holidays", to scream that Christians are being "persecuted" when science and not bible is taught in science classes and gays have any rights, to scream that Hollywood "hates Christians" because a movie depicting Jesus being tortured did not win an Academy Award. Where are they? Too busy trying to boycott Ford for advertising in the Advocate? Too busy trying to outlaw abortion to worry that their own religion is outlawed on pain of death?
Interestingly, the Council on American-Islamic Relations has denounced the sentence, saying religion is a personal decision that should not be coerced.
