True not all, but according to polls a majority do, especially in the US. If they did not then you can be sure that they would be doing more to combat the problem themselves.
Instead they say "Oh, we don't support violence but the victims have brought it on themselves." This is another way of saying US and Isreali citizens deserve to die.
If you refuse to recognize the enemy, they will kill you without giving you a chance to defend yourself.
I don't doubt there are some bad apples here. Let's take corrective measures. I think prudence is the only rational course here. I just want to make sure we don't over react.
