I’m not the right person to talk to. You should find the vocal BIPOC on masto.

But overall, mastodon is pretty white, in part because of the relative Euro-centrism of the place. And so whenever anti-BIPOC issues come up there is apparently a good deal of awkward defensiveness and silencing that goes on.

Beyond that, while there are trans/LGBT safe instances etc, no such thing really exists for BIPOC and the best attempt at one was shut down because, IIRC, of abuse issues. So generally, BIPOC people feel that their safety isn’t catered to well by admins and the software at a system wide level. A major issue being how a new BIPOC can sign up without worrying about getting abused on their new instance.

These are just my vague impressions though as a white person.

Structurally though, it kinda tracks, because mastodon is a pretty quiet suburban like platform while I sense that BIPOC rely on connecting with their community online. From what I can tell, white trans/LGBT people find safety on mastodon by finding smaller safe instances with defensive moderation and defederstion strategies. That hasn’t happened for BIPOC and may not work either (???)
