In undue fairness, a mod to downgrade nudity or vulgarity would kinda make sense, if someone personally didn’t want to see that. (Or if they were concerned about it for streaming. Or they had kids in the room.) For example, there’s some racial slur graffiti in Bioshock Infinite that is used for highly effective shock value and characterization, and I could see someone wanting to tone it down.
The root issue is what’s being removed: the abstract possibility of characters being called “him” or “her” independent of their appearance. To people who won’t use the feature, it is literally nothing. It simply does not exist beyond a checkbox they’ll scroll clean past. The game part of the game will work exactly as they expect, from start to finish.
They’re whining about censorship because the real purpose of this mod is to signal that they’re against anyone else having that option.
They are performatively upset by this trivial separation of character model and branch condition. Because they hate trans people. There is no other possible motivation, because this pointless change is simple and direct.
This removal is a website telling those bigoted trolls: poop in someone else’s yard.
