This argument is always brought up - "it was used centuries ago, so it's still valid now!"

Except: all normal human beings trip up on it; those who believe in the they/them BS trip up on it; and almost no one who uses this argument supports other things that were done centuries ago, so it's not really arguing in good faith.

Arranged marriages at very young ages were a thing centuries ago, should we bring those back?

If you want to use custom pronouns, nobody is stopping you. The rest of the world is just annoyed and tired of hearing you desperately announce it every time we see you and we're not going to play along.

I wasn’t using it as an argument for reverting to some past usage, just pointing out that language and grammar evolve. Just like it evolved away from that usage, it may evolve back.

I find the fact that some people are massively triggered by this fascinating. Personally I’m happy to use whatever pronouns people desire for themselves if they make it clear to me. I get it wrong occasionally cos I have a lifetime of doing something different, but if someone has explicitly made their desire known to me, I’ll make the tiniest effort of referring to them as they wish. It’s not a chore for me. I think of it as being polite to that person.

If I tell you my name is Mike, and prefer to be called that, would you insist on calling me Michael or Micky or Mickster? Even if I told you I was uncomfortable with that (for my own reasons which I don’t have to share with you)?

Im guessing “we” is not referring to yourself here.
