I think there is a difference. There are two version of Jesus, one mentioned in Quran and the other not. Western post-modernists ridicule their own Jesus as a deliberate movement subverting the foundation of Christianity. So Muslims will have little reason to shout for that.
But you might mock me by asking then why Muslims enrage when some one challenge their own beliefs most of them not Quranic? Would you raise this question or know the answer?
