If those on the left were genuinely concerned about the integrity of the First Amendment (as they interpret it), the same alleged “wall” that separates church and state would also separate mosque and state. Instead, the left celebrates not just teaching about Islam but actively proselytizing for Islam in the public schools. Why?

On their hatred of Christianity and contempt for the Constitution, both the left and political Islam agree.19 "
