Not all Muslims are terrorists, but the terrorists we fight are Muslims. If profiling Muslims at airport security checkpoints prevents a terror attack then by all means do it. I'm not Muslim, but if white males ages 18-40 suddenly went nuts and started blowing up airplanes then I wouldn't hesitate to let them search me if they asked. Noone seems to place any blame on the terrorists anymore. Most of the problems people have with the current US foreign policy could be answered if those people would take a step back and ask why they are needed in the first place. Everyone quotes Benjamin Franklin and our other founding fathers not realizing that times have changed. Terrorism as we know it today didn't exist back then. England was their common enemy and they wore red coats. It's not that simple anymore.
Sorry for the rant.
