Well, sure. I don’t want to play a surrealist freeform larp with a bunch of 16yo white boys who make gay jokes and have only ever played 5E. That sounds like a special kind of hell. But you kinda have to do that for a while when you run an open community, hoping they eventually grow up or go away and that slowly you attract a more diverse and interested audience. Or you build a smaller non-open community slowly, by invite, while trying not to look like elitist jerks. But that can be tough too.
