Well, I'm glad peace has broken out. But what do people propose we do?
Let's imagine Sage, a non-binary person who wishes to have the pronouns 'xe' and 'xir'. Xe puts 'non-binary' on BGA's shiny new option system and 'xe' and 'xir' into the new pronoun options. And imagine a status message that is currently '$PlayerName plays a card from $pronoun_possessive hand'.
For people who currently state 'Male', $pronoun_possessive is 'his'. For those who put 'Female', it is 'her'. Currently, if you put neither I think some games put 'his' and some put 'their'.
Problems:
1. What should be displayed for this status message in respect of Sage on other players' screens?
Possible answers:
(a) "their"
(b) "xir"
(c) "his"
(d) "his/her"
(e) something else.
Answer (c) is historically what you put when you didn't know someone's gender. Up until fairly recently, (d) might have been used, and (a) was also becoming more accepted.
Perhaps (b) is gaining in popularity. But some people, particularly older people or people who want to play in English but whose native language is something else, may not recognise 'xir'. Is it right or fair to risk confusing them because Sage says so?
And what if some prankster puts, say, 'you/your' as their custom pronouns? That might be very confusing to other players.
My gut feel is that there's no answer to 1 that will ever satisfy everyone, so maybe doing nothing - although clearly flawed - is better than spending a lot of time doing something that still won't make everyone happy.
2. What do we display for this status message in respect of Sage in other languages?
Possible answers:
(a) Forget about it in other languages.
(b) Ask for custom pronouns in every other language.
Both the answers to 2 seem pretty bad... can anyone do better?
