The point is that acts of terror are committed by people of all races. This time it was Arabs, the next time it might be militant Neo-Nazis from the midwest. Or French Canadians who want to "liberate" Canada.

If you limit your sample size to hijackings which turn into suicide attacks on occupied buildings in busy American cities then yes every single time this has happened it has been an Arab, then again its kind of a small sample size so you truly can't make any kind of statisical findings that have any relevance. After all every single one of those incidents occurred on September 11 . . . would you conclude therefore that it is safe to travel on every day other September 11?
