If people want to be part of a limited community that’s fine and well. The issue I have is that a lot of people joining lemmy don’t know what beehaw is about and join it just because it’s a name they’ve maybe heard of. Then they’re completely unimpressed by lemmy, not knowing they’re only part of a fraction of the federation. Next thing they’re back on reddit or whereever.
Also, as someone with access to the majority of lemmy instances, I’ve only ran into maybe a handful of assholes on here. I’m really not sure what beehaw is trying to shelter it’s users from. It’s easy enough to block someone on the rare occasion.
