I know that many people will say that this is easier said than done, but I have always done my very best -- in a number of encounters over many years -- to exercise my constitutional right to remain silent when confronted by TSA personnel or even by true law-enforcement officers. I respectfully refuse to answer questions (beyond identifying myself) without consulting a lawyer. I ask repeatedly if I am under arrest or being detained. Once, after a cop who was trying to question me in a shopping mall parking lot -- about something having little to do with me -- told me that I was not under arrest, I asked, "Then I presume that I am free to go?" He said yes, and off I went.
Cooperation with fascists just makes them stronger. Resist and make them uncertain of their authority. It's good for the country -- really!!!
