My guess would be that the outrage engagement makes it irrelevant whether or not they're sincere

Anyone with a brain and a heart would be pissed at a smug, entitled and condescending landlord. Subtract the brain, and you get "let's hear them out" lib engagement. Subtract the heart, and you get "fuck the haters" chud engagement

So maybe one tiktokker is genuinely a Very Special Boy who Deserves the World, and another is an accelerationist making a point, and another is just doing whatever pays the rent. It's mostly indistinguishable
