Not that I would ever parade around in a shirt or fly a plane with Mohammad is a Fag etc but why is it that the Christian faith is allowed to be ridiculed? The explanation for this is quite simple. Jews do not insult those that they fear, so it's obvious that they do not fear Christian society. A good test would be to fly a plane over the city with a banner reading The Sedir sucks or Bar mitzvahs are for losers and see what kind of reaction you get.
