>Don't be an asshole.

Oh, the irony!

>Parent misattributed the pronoun, sure. And then they were asked to not do that

Not sure at all that they misattributed anything.

And they weren't asked. They were lectured "on principle". And not even by the supposedly offended person, but from a third party that had nothing topical to contribute to their discussion.

Imagine for a second that you were constantly being assumed to be an incorrect gender. And let's further assume that it bothered you. Would you want to spend all your time telling people to not assume your gender (and consider the high possibility that they're going to get a reaction like this)?

No, you're not. And so every dude on this thing is going to use "he" everywhere cause "no-one's complaining". And then when people who prefer different gender pronouns come in, they're going to see people being assholes about gender pronouns, and they're going to say "fuck this" and leave (note, they're not going to reply either, cause they also are sick of it).

And so to prevent that, people other than the "supposedly offended person" need to step in, even if they weren't asked.

I'm not going to reply to further discussion here. I hope this was useful to you.

If it bothers you, you can choose not to be bothered by it.
