when someone from an elite victimized class explains to a member of a majority group how racist, sexist, homophobic, trans-phobic etc they are without any evidence of matching behavior or thought patterns to support their case. They often surround their accusation of bigotry with "weasle-words" like "subconscious", "passive" or "benevolent" to soften the blow of their "guilty-until-proven-innocent" stance. Disagreeing with a Hatesplainer is considered by them to be morally unacceptable, as they are generally incapable of tolerating any "diversity of thought".
These LGBTQIA+* people in some chat room are hatesplaining to me how racist, judgemental and hateful I am. I'm not oppressing anyone! They don't even know me! In their delusional world all white men are evil. Whatever happened to being judged by the content of your character?
