I respect Kae Tempest can make up Kae Tempests own pronouns, in return Kae Tempest can respect that i can make up my own also.
Actually I don’t think you should. If Kae has made it clear they want to be know by they / them pronouns then out of courtesy you should do it. It’s a very sensitive subject in the TG/non-binary community and it’s up to us to learn, not just say ‘it’s confusing’. Sure, we all make mistakes but then we say sorry and try to not do it again.
If a new work colleague, Christopher, started and you called him Chris, and he said ‘Actually I don’t like Chris, please can you use my full name’ is it OK to continue to call him Chris because ‘you’re allowed that privilege’?
On a side note i quite like er er er er lets just say Kae
You didn’t make a mistake there; you knew what pronoun to use and chose not to to make a point. That’s not right.
