It's an unclean, perverted goon squad
the idea of groping or even touching/feeling the clothes on private persons, as if they were cattle or property to be inspected is a great moral evil. It is un unholy and unclean practice inviting unwanted looks, touching, etc. Even the forcing people to remove shoes is an evil, because socks are underwear and shoes are clothes, and asking anyone to remove a piece of clothing that exposes their underwear or flesh is wrong in many ways. It is also unclean to allow oneself to be publicly humiliated (remove clothing) when one has done nothing unlawful. The day I am ordered by one of the TSA goons to the side for the government-paid molestation and pervert-petting session will be the day I just say no. There are rental cars, busses, etc. It's against my beliefs to be touched by strangers or to remove clothes in public places.
