Dear "concerned and outraged".
What are you so concerned about? What exactly is so "private" that you need to hide it. Do you think that the screeners really care what you look like under your clothes? You and your privacy advocates need to grow up and face the fact that we live in a world where people are trying to bring harm to others. And no, this is not a "profiling" thing. The danger could come from anywhere and anyone. Stop worrying yourself with everyone's rights. What about my right to a safe flight? If something terrible were to happen, I promise that you will be the first one to say the Government isnt doing enough.
