Japanese community don't do that because they hate English speaking people or because they don't understand it, they do that to filter typical mess that is in public worlds, people who don't care and not even interested to interact normally and just mess around. Same thing that english people hate and avoid public instances. And since most of them don't speak English they don't have means to talk back and moderate, which is reason why Japanese groups have rule to know english
I feel like we should be like the japanese community on vrchat and make english, korean, portuguese, and etc quizzes for the worlds
Vrchat supports the japanese quizes
I'm sure they'll support the rest of the gobal community with their's
