It's the day ordinary citizens stand up for their rights, stand up for liberty, and protest the federal government's desire to virtually strip us naked or submit to an "enhanced pat down" that touches people's breasts and genitals in an aggressive manner. You should never have to explain to your children, "Remember that no stranger can touch or see your private area, unless it's a government employee, then it's OK."
The goal of National Opt Out Day is to send a message to our lawmakers that we demand change. We have a right to privacy and buying a plane ticket should not mean that we're guilty until proven innocent. This day is needed because many people do not understand what they consent to when choosing to fly.
The bottom line is that flyers are in a no-win situation: both the naked body scanners and the enhanced pat downs are grossly violative of our privacy rights and dignity, both make you feel like a criminal. At least when you choose a pat down you can look the at the government official eyeball-to-eyeball when you're getting touched, and there are not lingering questions about safety and just what is happening in that back room. Is there really no better way to provide aviation security than an inappropriate touching or a naked body scan?
