Thing is, they can't really hurt TERF Bitch Joanne in a way that matters. Their usual M.O. of getting you fired, ostracized from wider society, and deplatformed, doesn't work against someone that has "fuck you" money, is their own boss, and sticks to a platform--Twitter--that has no interest in banning her, with that being even less likely now that Musk controls it.
So they project all their hatred of TERF Bitch Joanne on the only other outlet they have--Hogwarts Legacy. This is why they go into hyperbole with things like saying buying HL promotes literal trans genocide, and having an OT for HL is on the same level of having a KKK rally.
