I just finished a book about this very subject. It talks about how Christianity is becoming somewhat of a punch line as people get "smarter" and fall away from religion. Thus, there is a vaccum that needs to be filled, and Islam is the "new" thing. That's oversimplifying it, but I believe it to be true. Also, with how people are afraid to mock Allah or Muhammad, because of fear of being killed, but it's nothing to see Jesus being made fun of on SNL. I am not religious, but see the value in Christianity during these times.
