I can only imagine how difficult it must be to identify as non-binary.
When you’re non-binary, being misgendered is an occurrence that is both frequent and incredibly awkward. Most people outside the LGBTQ+ community (and a good number of people within it) automatically assume that everyone they meet is either male or female. This means that when I meet someone new, there is a pretty good chance that they will read me as one of those two things.
I am guilty of this as well. To the best of my knowledge I don’t know anyone that is non-binary. That isn’t an excuse. I might never hear that someone is non-binary if I can’t help them feel comfortable telling me.
