I have observed that many posters who are indignant that they were selected for/channelled into/were asked for their name or denied some presumed privlilege have to state somewhere in their post that
"they look nothing like a terrorist" and also state that they are "caucasian" or "very white" as is the case of the OP here.

I would like to know if you feel that this it is alright for these idignities to be done to people who in your minds "look like a terrorist" whatever that may be....

The TSA idiot who stands on the other side of the backscatter/Xray machine usually stops people who are not white on some pretext or the other and subjects them to a pat down or finds an excuse to touch them in some way before they can leave the area. That person, like the OP, unfortunately has no recourse but to subject themselves to the pat down because they have "to complete the screening process".

Also, I have observed, the TSA idiot does not usually subject african american persons to this because that might lead to a charge of .....

In my experience, the idiot will refuse to:
1) let you see the scanner image that shows the anomaly (so that you can make sure there is NO LINT in that pocket next time)
2) to let you go through the scanner again (to validate the alleged anomaly)

and they will lie to their supervisor about your attitude and behavior (which was fine until TSA idiot suddenly stuck their hand in your face and began touching your before saying anything to you.

Even though I have NOTHING in my pockets, wear light clothing, and only have the the plastic buttons that fasten my shirt, pants, and button down collar (!) when I go through the X-ray/Backscatter machine, I am always stopped usually in a very rude manner by the idiot who wants to do an additional screen.

The supervisor will always support the idiot and the LEO will support the supervisor. This is almost guaranteed to happen and surprise, surprise if 2 or 3 LEOs do not gang up on you afterwards.

These are the facts for people who are not white and who are not black.

So please bear this in mind when you become idignant about your treatment, or get snarky and mispronounce or refuse to pronounce your name for the name game.

Signing off as "disgusted that more Caucasian people do not write their Congressmen to change these draconian laws"....

That said, I do feel for the OP for what they experienced.
