yeah but "their" has already become so commonly used that it's technically fine to use it
He started it by saying ‘their’ was more correct lol. ‘Their’ is still incorrect, technically. That’s like saying if lots of people murder each other it means murder is okay.
Nah because there are people who will never change their opinion on murder, most of those who are religious will not even murder. Unlike this, the English language is ever changing, and humans shape the way of this language. Nowadays, when you speak, you may use "their" because most people use "their". And plus, it is much better to speak (only informally) "their" instead of highlighting the possibility of the gender. Will you say, his/her/non-binary? I don't think so.
You said I was wrong. When I was proved right you start this strange… thing. Admit your mistake and move on. “Their” for singular is technically wrong. How is it better in informal speech?
You literally said I was incorrect lol
