It's a few seconds (note, few seconds, not constant exposure) of radiation, and your body has mechanisms to reverse mutations. I think you're getting too hung up about X-ray radiation, which is a general term from simple body scans to MRIs. If you are really that worried, take your cell phone out of your pocket and put it in a man-purse or something.
It's not about the X-rays or the pat-downs.
It's about our rights, man.
If we don't defend them, they will take them away from us, one by one. We need to defend our rights.
These searches are ridiculous. Innocent before proven guilty. This treats us all like we're convicts carrying guns or whatnot. And yes, security is important, but what's the limit?
Why bring a case upon a man who refused to be groped around his genitals? He left the airport, if you saw the video.
There's no need for this.
It's about my right to privacy. No one can tell me to take off my clothes and search me without a warrant for arrest. No one can touch me all over without a warrant for arrest.
