Do you honestly doubt that? I've tried to give it some heavy thought, and I think you're completely wrong on this point.
I can't speak for everyone, but I do not mind people saying that there are many muslims who choose (and teach) violence - it's obviously a fact. I do, however, mind people claiming that my own religion was never supported by violence and never deserved the opportunity to evolve. I feel we have to offer the same chance to this religion, w/o legally backing the idea that a whole group of people should be judged as potentially violent. For me, there is a difference between knowing that there is currently much unrest in primarily Muslim countries and saying it's ok to treat anyone who looks like they belong there as a potential criminal.
