It was mocking a long-time user, @BrookeBaybee, who recently left (I think?) due to the influx of transphobia trolling. Brooke made a lot of "I love my trans comrades" posts over in !transenby_liberation@hexbear.net, which is what @BASED_BALL was making fun of in that post. She had been making those posts every day since the pronoun shitshow a few months ago as a show of solidarity. I'm sure B_B meant it as a joke, but it was really fucking tone-deaf and just exacerbated the shit that our trans users are already going through.
