no, it's pathetic, pointless and an easy target. at the most you'll get some funny looks, a few tuts and the odd few giving you some verbal.
if people really wanna be controversial, why not wear a tshirt saying 'fuck mohammed' in an area with a large muslim population? yeah, that's right... they'd be dead within minutes 
this guy nailed it..............its a phony attempt at being provocative and contoversial
christianity is SUCH an easy target, anyone can say anything about it, its not shocking anymore
try wearing a shirt like that about judism or islam...........then the guy would be a a "rebel"............this guy is just a white-guilted, self-loathing pussy
