I'm not sure this is the message I'd teach my children: "Don't let strangers touch you. Unless they are from the government. Then it's okay."
The video makes the claim that the TSA are well-meaning people just here to protect you. This is false. The TSA is a branch of a government that exploited 9/11 in order to grab more power.
This last year, I've flown from Europe and Japan back to the United States. In these cases their security did not demand access to my genitals, yet the planes landed safe in the United States without crashing into any buildings. I'm pretty sure that for flights departing the United States that there is little marginal benefit to screening people's privates.
PS: I may have taken a few liberties in the interpretation of the video :)
