I don't think there is anything at all exaggerated about this being sexual assault. It's far past anything you'd get anywhere else outside of a pre-prison/jail search.
I don't want to argue, but my point is that there surely will be specific TSA agents out there who will abuse their authority in perverted and illegal ways. It would be a shame if complaints against them were buried under complaints from people protesting the policy that the entire agency is operating under.
It's exaggerated because he's intentionally trying to provoke a reaction. It's better that you just let them act unprofessionally all on their own, and then go file an official complaint and another with the ACLU here: http://bit.ly/9KOipo
