I really wish they would stop limiting our freedoms with artificial security measures. The only security concerns about airplanes should be weapons or explosives on board. Therefore, they don't need an ID, a gender, a name, or any information at all about you. All they need to be doing is searching/screening people and bags that go into the secure area. Who you are doesn't make one bit of a difference if you aren't bringing something illegal. This is all just BS. I can see the airliner itself requiring that you prove the person on the ticket matches you simply to prevent ticket fraud. As far as I'm concerned all of these other artificial security measures are unconstitutional. As long as you aren't bringing a gun or a bomb on board, the government has no need to know who you are, where you are flying, or why you are flying. Don't tread on me!
