I don't owe you a history lesson with citations and interviews, and some kind of harm analysis, to prove to you that white trans women are very oppressed just because you can scream "white" at me, or just because you're deeply oppressed too. And I certainly don't owe you perfect angelic benefit of the doubt, the assumption of a perfectly good character, and a nice, sweet, helpful tone, if I think you might be being bigoted. If you do or say something that looks bigoted against a group, don't expect people in that group to correct you nicely and get mad when they don't, even if it was a mistake. Because in their day to day experience, usually it ISN'T a mistake.
