Performatively pretending to support movements against oppression is just no longer, in any way, less frustrating than the conservative tendency to just outright support oppression, and that's all liberals do.
Obviously, conservatives are evil and huge pieces of shit, but I'm at a point in my online presence where I just expect the most brainlet shit from them.
Libs, on the other hand, are just in an indefinite cycle of spouting bad takes that enable oppression, but due to ignorance, they think they're actively helping fight against it.
As a trans person of color, bigotry from conservatives is phasing me much less nowadays, but racism and transphobia from libs now seems significantly more abhorrent.
Don't expect me to explain the psychology behind it. This is just how it be like sometimes.
Just to add on to what you said, but tying it with the bit from OP you quoted.... I don't think that was ignorance or them thinking they were actually helping fight against oppression. It was purely a performance to try to co-opt the liberation movement and remove its teeth in order to render it harmless. They weren't being good-intentioned but stupid, they weren't thinking they were "actively helping fight oppression" just in an ineffective way, rather they were using that pretense as a tactic to fight for oppression in a way that benefits them. And it was effective.
