Yeah, I’ve done ALL of that (well, maybe not traveling while brown), but never so dramatically as you describe, nor have I ever witnessed it. ALL of your situations are greatly exaggerated, or were provoked. Nobody has EVER "screamed"at me about touching my bag, that’s just silly. I’ve never seen anyone scream about anything in a baggage inspection line in my life.
These people are doing an endless busy boring job, and they generally do it standing up all day, so I don’t doubt they don’t have the greatest job satisfaction in the world. I don’t expect them to kiss my ass for the privilege of serving me, just be professional and efficient, and they are always that.
I often travel with specialized equipment in my carryon, and I EXPECT it to be pulled out for inspection. I have definitely been inspected FAR more than most other passengers, and in fact, I am surprised when they don’t. Sometimes I see them all gathered around the screen, peering and pointing, and I’ll call over “You’re probably gonna wanna inspect that,” and they all turn to look at me, and then they pull it off the belt, and bring it over for inspection, but not always. I once asked why NOT one time, and an obviously very experienced agent told me what all the items were just from the X-ray. I told him I was impressed he was so accurate, and he just smiled.
Perhaps your TSA problems aren’t with TSA, they’re with you. They are always polite and understanding when they inspect my bag, and let ME re-pack it right there at the inspection station. Are they smiling? No, they tend to be stiff at first, because they are anticipating a passenger like you, but they relax when they see I hold no animosity for another American worker, just doing their job. I often walk away with both of us smiling, because I give them a rare moment during the day when they aren’t under attack.
These TSA workers are our neighbors, our friends, even our family members. They are doing a difficult job, without a lot of pay, and people like you giving them a hard time all day, every day. If you aren’t getting the TSA experience you think you should have, maybe try a friendlier approach. It also tends to succeed in a lot more circumstances than just airports.
America is in a weird place right now, and these government workers are stuck on the middle. They aren’t responsible for anything, they’re just a cog in the wheel, doing it for a paycheck. They are exactly like the rest of us. Our beef isn’t with them, it’s with the psychopaths at the top. Beating up on our working colleagues doesn’t do anything but drive our collective morale even lower, and it isn’t even satisfying.
Save your animosity for those who deserve it, and support ALL American workers. They’re the Good Guys.
