My sister called me racist 11 years ago for something that wasn't even racist. I just didn't understand the concept of white privilege because I was being treated like utter crap by everyone despite being white (turns out that was down to not having neurotypical privilege, but I didn't know I was autistic at the time). Since then I've been looking for opportunities to call her racist so we can get even. I'm so annoyed, I had the perfect opportunity to get back at her today when she referred to locs as "dreadlocks" which I've heard some people say is racist. But I chickened out. I know it would have caused drama, but it would also have been very satisfying seeing her face when I call her racist. It's okay though. I have kept bringing up the racist thing she said when she was 9 to get back at her. I reckon she remembered what she said all along and was just calling me racist to make herself feel better about it.
