It’s really really ignorant to not know that was going to cause offence to Μuslims. The reason it was so well know is the riots it caused. So I think he knew he was going to cause offence.

And it’s not just Muslims, there are plenty of dangerously crazy christians (too much of the US!). I’d wonder if it was monotheism being fundamentalist, but then there crazy Hindus and Buddhists and everything else. I think it’s just humans. Especially in groups/mobs.
