One of my friends has so bought into gender ideology that he refers to almost everyone as "they/them/their". I can never tell whether he is talking about a man, a woman, or a group. It's so confusing!

I think this originated when he realized he was bisexual and started trying to date both men and women, but didn't want to reveal the sex of whom he was interested in. So, internalized biphobia feeding into gender ideology. He's "nonbinary" now himself, no surprise.
