Generally the TSA x-rays my bags looking for weapons and makes me walk through a metal detector, then I go on my way. Sometimes the line is 15-20 minutes, though usually it's less than 5. Sometimes there's a millimeter wave body scanner that some might find intrusive - personally I couldn't care less if a TSA employee sees my junk, and those that object can opt for a pat down. Those that object to being touched might be better served by a therapist than a plane ride.
This objection to flying because of the TSA is a psychological problem on your part and has nothing to do with reality. Unless you are carrying prohibited items - knives, liquids, etc - you will almost never encounter a problem with the TSA. Sure, the rule may be arbitrary and ridiculous, but they are not particularly onerous or oppressive either. I certainly make comments on bad policies and advocate for change. The system is nowhere close to the gestapo crazies seem to make it out to be.
Of course, you're likely psychotically obsessed so this will mean nothing to you, but get some help.
