Incidentally, most atheist I have heard are sympathetic to Islam as opposed to the other two religions (Christianity and Judaism). It is annoying for me to hear athiests -- many of them -- talking about how they are for reason and logic and then embrace the most anti reason and anti logical of the religions. The Muslim religion rejected reason and logic when they did not adopt the views of their greatest philosopher, Averroës. This is in contrast to the Christian religion that was given Aristotelean philosophy by those church giants, Albert Magnamus and St. Thomas Acquinas.
The atheist libertarians are soft on Islamic terror. Which atheists do stand against Islam? The execrable, Bill Maher, and some followers of Ayn Rand.
Many atheists are against Christianity mainly because they don't like disapproval of their lifestyles.
Islam is a religion of plunder which is OK with sexual slavery. As such, it appeals to a certain personality type.
