I definitly did not mean to imply that black and non-binary are mutally exclusive. I am sorry if I gave off that impression. It was not my intention.
Again, it is what I was told when introduced to the term. I tried to imply that I am a bit sceptical of it. It also sound to me like an internet things, because phonetically I can hear no difference betweem NB and enby.
People sadly do fight over acronyms, though, and call people all sort of horried things for it. I have for example seem some ugly fights over the A in lgbtqa.
I am glad to hear that a person who is black saying they have never heard of it though. Then I am just going to write it off as some white people getting offended on poc’s behalf. That has happen before.
