Yes, but we must remember that Muslims=/=terrorists. CrabCake is right- satirise the terrorists, not the whole religion. Sadly, I am seeing some right wing outlets in the US paint the magazine as a anti-Muslim outfit that affirms their prejudiced views- never mind their strident anti-Christian views.
I get what you're trying to say here, but I think we have to be really careful with the distinction between criticizing Islam and criticizing "all Muslims." These are way different ideas, and I often see people treating them as the same. There are obviously some Muslims with totally unproblematic theological views. Does that make it unfair to criticize Islam generally? I don't think so. In some cases, the problematic theological views are majority views in many (or even most) countries. I think it's totally reasonable -- even responsible -- to note that these being common views doesn't make them universal. Ditto for noting that most Muslims who hold theologically troubling views never commit acts of violence. But I've also seen people take this further, and claim that troubling theological views are rare
because few people commit violence (demonstrably untrue); or that these views have nothing to do with religion (ridiculous); or that it's unfair to criticize a religion for beliefs in it that aren't completely universal (totally impractical).
(edit: yikes, that was a long paragraph. I hope you get the general idea...)
