Thanks for your reply - I'm not the grammar police, but then everyone else seems to turn into sociolinguists whenever language evolves in a way they don't approve of, so make of it what you will.

Language evolves - all language. Unless you still refer to yourself as a 'gay girl' and to men as 'knave girls' (https://www.huffingtonpost.co.uk/entry/history-of-the-word-girl_n_57bb6915e4b0b51733a5319)

- in which case, well done on learning how to use the internet.

And, for that matter, we're not speaking about other languages - the users of which are far more qualified to speak on inclusive language within them than I am. We are speaking about English - a language which has had a singular they since the 1300s (https://public.oed.com/blog/a-brief-history-of-singular-they/)

More than that, we're speaking about respecting someone's identity as being beyond the male/female gender binary - whether you understand that or not.

It's not bigotted to struggle with changing usage and terminology - it is bigotted to choose this moment to become all-consumed by the rules of grammar, which are not in your favour.
