You honestly are throwing me a stumper of a question.....how is it possible to be sexist to someone who claims to be non-binary? A legitimate question.

If you're not claiming to be a woman, then I can't be sexist against a woman because your not a woman. Not a man, so can't be sexist against a man.

So how can you be sexist against someone who is neither man or woman?

Edit: And blocked. I guess they didn't want to explain this one.
