Comparing TSA employees to the people committing war crimes during WWII is a gross overstatement if not logical fallacy. TSA employees are not "just following orders", they are following what they believe to be the morally best course of action to screen people of potentially dangerous items.

Also, TSA employees are human beings, not robots designed to ignore impolite behaviour and programmed to always deliver polite behaviour. As a fellow intelligent human beings we must understand our own limitations and the limitations of the world in which we live, and strive for mutual understanding rather than wear an attitude of self entitlement.

The TSA is partly responsible for huge numbers of people refusing to visit the U.S. for business or recreation. Think of all the U.S. cities, counties, and states spending money to get people to visit, yet many people think, "Get on a plane and allow my daughter or wife to be molested? No thanks."

Touching another person's genitals without permission is sexual assault, and many people will not put themselves in that predicament.

Why do so few people get this? Why, for example, do people continue to insist "the war is unjust, but I still support our soldiers"?

They're the same soldiers we would expect to fight the just wars. It's not as if they're the ones starting these things.

Why? Because many of the soldiers are their family and friends.
