not that everyone (or even most people) believe what they're feeling is hatred. maybe you call it "deserved justice," or "an eye for an eye" or "harsh but necessary."
but if you feel Schadenfreude - catharsis or pleasure from someone's suffering - then you're feeling hatred.
as a trans woman, I (and my people) are often on the receiving end of this. to be clear, I'm not saying that any opposition to trans rights is borne of hatred, any more than any support of border enforcement is hatred. but if you feel that catharsis at the anguish of a group you oppose, be honest with yourself: why?
