What you are talking about is the classic leftist hypocrisy - "it's funny when we do it, and xenophobic racist nazism when you do it" Colbert and the like made a career criticizing conservatives and made Christians look like kooks. That is mainstream now, and has caused unbelievable harm (undeniable influence of the antifa movement).  But God forbid conservatives "parody" Islam. Notwithstanding that it could literally result in death (Hebdo), closer to home, it manifests in the form of some ridiculous anti-free speech legislation. Textbook left.
