You missed the point of the comment you’re replying to. To a lot of people, garden-variety binary trans people are “absurd and contradictory to reality”. To even more people, nonbinary people are.

Blahaj lemmy’s admins have decided that they will not draw a line, because they don’t want to be the arbiters of what is valid. That does mean some extreme cases don’t get decided the way you would, and that’s fine! Just block those cases.

Whatever identity they have, I don’t care. The internet’s big enough for everyone. It’s not my problem, not my life, live and let live.
