For reasons that are beyond me to explain, Christians have come up with and use crass language involving Jesus /god and rarely speak up if they are offended.
Jesus ** christ! Is not a Muslim way of cussing, it's origin is Christians. There is no typical way that I've heard muslims use to be crass with the name of their prophet or god.
I have heard Christians make claims about Muhammed that muslims disagree with. They do so on Christian talk shows, right wing talk shows, and I don't think Richard Dawkins holds back on his opinions of islam.
Cussing out muhammad is not part of Muslim culture while using Jesus as an explitive is in Christian world. I have seen muslims object to usingname of Jesus to cuss with.
Crazy muslims think it's fighting over if muhammads name is disrespected. It still happens and people do, but sometimes a whack job decides to make a point on this subject and harms others. It makes the news, but bill o Reilly doesn't censor himself. Plenty don't and they aren't all anonymous.
If Christians slowed down seeing movies where Jesus name was denigrated, then it would end in the movies.
