"The vast majority of rapists are men. Therefore, the vast majority of men are rapists." That's the type of logic some seem to be using on this thread.
I've got no problem with profiling as a police technique. It's foolish not to pay additional attention to young moslem males in places like airports. But that's just a common sense precaution. If only .1% of young moslem males are terrorists, but only .0001% of the general population are terrorists, it makes sense to focus on those young male moslems. But that's a lot different from condemning all moslems for the actions of a few.
