There cannot be topics forbidden to be made fun of in a free society. If we cannot make fun of Muslims and Islam in any way without causing religious riots and violence then current form Islam has no place in a free society. The difference between Islam and the other monotheistic abrahamic religions is that the older two of the three have had enough time to go through cycles of reformation and ideological modernization, making them somewhat compatible with a modern pluralist society. Islam still insists a bunch of fables from when the book was written are literally true and valid today, and not just apocryphal advice on how to be a decent person.
And before someone brings up the inevitable American evangelicals as comparison, they are equally incompatible. Luckily that scourge is largely confined to the United States and not my problem.
