Nothing about this is "fair" to Black people.
In the long run, maybe #Mastodon and the #Fediverse could become a better haven for Black people. But that will require a lot of work and self-reflection by the people who are currently shaping the discourse around here - starting with reading up on why #BlackTwitter bounced off so hard around here.
And it goes further than that - I mean, by all accounts Mastodon is still overwhelmingly white and European / North American. There is very little representation from, say, Africa or South Asia.
And if people from these communities don't come here because they feel they would be screaming into the void... well, the best we can do is listen to the concerns of those who _are_ sticking around.
