They love trans people in the abstract, as an innocent victim they can "protect" from the republicans. They hate actual, real world messy trans people, who act like human beings instead of idealised victims. Same with any group libs claim to care for really, they only like them when they are victims in need of protection, and hate it when they stand up for themselves.
To liberals, holding the right opinions is praxis. Having done their "praxis", they can use it to bludgeon actual leftist praxis, lest you interfere with the benefits their performance provides.
They achieve not trans, indigenous, or queer liberation, but a feeling of superiority and self content that provides enough moral licensing to justify whatever bastard shit they need to excuse. Being a good opinion haver™ lets them continue doing nothing with their ego unscathed.
This strengthens the dialectical relationship between doing nothing & reaction, effectively putting action in the corner. Status quo maintained.
The ol' TC gave Hexbear the tick of approval? I'm shocked and surprised. I would've thought he'd have never heard of it, but apparently he's your biggest fan! I'm sure this person has a very solid and reliable source for this and certainly didn't just pull it out of their ass.
