I'm sure anyone who is selected for screening feels singled out. It's only natural.
Like in Policing, it's a woman making contact with a woman, even though guys can see the screening image, the guys aren't making contact with the woman. In this day and age, when people put bombs in their underwear, and such, this type of screening is necessary. Even racial profiling is necessary. It's used by police, and is effective when looking for certain things. People need to quit being so sensitive. There are obviously pervs out there, and those cases can be handled on a case by case basis. That doesn't mean the whole system should be scrutinized.
