There's enough muslims in the world that most people should and probably will realize they aren't all murderous terrorists. I think people realize that terrorism is the enemy, not islam. Unless you're Israeli.
Islam is a religion with a strict code, and radicals willing to enforce it by any means necessary.
Other such entities were those like the nazi party, or the catholic church of old, which started the crusades.
Islam is therefore violent, as long as it's code is so strict and calls for such enforcement.
