I do not see how doing that is policing better than applying the same security regulations to everybody. When you apply to everybody, there are no loopholes. Essentially, you do your checking, and if you have probable cause, you pull them aside for more in-depth checks.
The neo-cons have spread the seeds of paranoia well, and people are just willing to let them do whatever they want. It's like people throwing off their clothes to get beads at Mardi Gras.
I think we need to accept this as a risk of flying and make decisions accordingly. I don't think we can ban and profile ourselves into any additional level of security, and you're tromping all over people's rights and any form of ethical fairness while you are at it. The day we purposely add ways tp treat people differently because of race and religion, is the day we take a major step back as an ethical and free society.
