I'm firmly in the left wing camp but if anything shits me about some of my fellow small L liberals it is their addiction to cultural relativism. Liberalism first and foremost is about individual liberty... freedom of speech and expression, freedom from violence, freedom from religious persecution etc.
Yet all that goes out the window for some because somewhere along the way they misconstrued criticism of ideas as somehow equating to an attack on the people expressing the ideas. And when the people expressing those ideas are from another race or culture, somehow it all gets misconstrued as racism as well. Ben Affleck I am looking at you, you insufferable douchebag.
Thus Islam finds itself on a pedestal among some western liberals. We are welcome to criticise Christianity (and believe me, I do) but we have to sit by while a father in Iran cuts open the forehead of his infant son with a machete as a bloody tribute to Allah, Egyptian infant girls have their clitoris sawn off, 9 year old Saudi child brides are defiled, women are stoned to death without trial merely for having an affair, and western journalists/artists/cartoonists are slaughtered because they drew a ******* picture. We are expected to sit here and say "oh but you need to interpret it all through their cultural lens...".
Stupid ideas deserve ridicule. And like all Monotheistic (and other) religions, Islam has plenty of stupid goddamn ideas.
