I really like this idea from Jeffrey Goldberg:
November 24th, as many of you already know, is National Opt-Out Day, when airline passengers should refuse to submit themselves to those privacy-invading, genital-picture-taking, radiation-delivering back-scatter imaging machines now installed at many American airports. ...
By the way, it is the official position of Goldblog that everyday is opt-out day. There's no need to wait until November 24th. But come November 24th, here's an idea you might try to make the day extra-special. It's a one-word idea: Kilts. Think about it -- if you're a male, and you want to bollix-up the nonsensical airport security-industrial complex, one way to do so would be to wear a kilt. If nothing else, this will cause TSA employees to throw up their hands in disgust. If you want to go the extra extra mile, I suggest commando-style kilt-wearing. While it is probably illegal to fly without pants, I can't imagine that it's illegal to fly without underpants.
Give the government gropers at TSA a real thrill.
