I can promise you TSA doesn't give a flying fuck about anything besides the water bottle in your backpack. Other agencies, sure, but the TSA itself is only concerned if you're trying to bring a prohibited item through security. Unless the FBI has tagged you as a terrorist or something they could care less.
Edit: yeah there are still bad actors and racists out there, but I'm trying to say that the TSA agent isn't gonna stop and go "wait a second you posted cringe on twitter" unless another agency tells them to. "But my agent was a jerk and profiled me" yeah there are jerks, it's surprisingly low effort to be an asshole. I'm just saying TSA (and just the TSA) has their head too far up their ass and is too lazy to try and monitor every single person who wants to take a flight themselves.
