Atheists on the Left oppose Christian missionary efforts in Iraq because they say we violate their “religious sovereignty”. Freedom of religion is a universal right whether all nations respect that right or now.
Freedom of religion that includes Islam, however, is suicidal because it can only work in one direction.
Until I can walk the streets of Makkah and visit the inside not only of the Great Masjid but the Kabba itself as a Kafir (non-Muslim), I grant no concessions.
I'd go further and say that Atheists on the left oppose anything Western. They love Islam because it's anti-western, anti-capatalism and to a leftists twisted thinking that means it's liberating. Of course most leftists don't understand that islam is a warrior based death cult and you either convert or die. Of course "people of the book" are privileged since they're allowed to live as second class citizens. In an islamic country any outspoken atheist would be killed.
