"I don't know about you, but it took me a while to become comfortable with the idea that people have the right to choose their own pronouns"

I don't know about you, but I don't think I'll ever be comfortable with the idea that anyone would give a shiat.

I know it's not quite the same, but for years my father-in-law was Dick. One day he said he preferred to be called Richard. It wasn't a big deal. It wasn't something anyone had to "be comfortable with." He was Richard. Sometimes he'd get called Dick just because habits are hard to change, but no one demanded since he was once Dick he had to forever be Dick.

If you have a problem with how someone else wants to be known or referred to, it's exactly that. Your problem. Keep it to yourself.
