@futurebird & I hope you are successful, truly. I know that folks you would bring here would enrich the space, and I too am definitely NOT content feeling isolated from Black folks on my primary social media platform.
I think I just lost faith that this space, in the short term, is going to become any less antiblack than it has been. I see a lot of potential in it, and I'm going to keep working to improve my server to make it more welcoming to multiply marginalized folks (and less connected to bigots and fascists).
But for me, I feel like until some big shifts happen in the culture here (some examples might be: a bunch of Black folks join the fediverse, or the white folks who are already here wake up to how alienating the place is and work to fix it, or we get a solid alternative to Mastodon that has a more flexible dev team and safety features get implemented ASAP, you get the idea) then I cannot pitch it to folks without massive disclaimers.
Why would I advocate for my folks to come here when I've so frequently experienced slurs, racist harassment, misgendering, and constant minimization of my experiences? When the vast majority of instances don't lift a finger to actually do anything about it, and the ones that do get harassed by racists until as often as not they shut down and leave? When people froth at the mouth if you mention fediblock or TBS, two of the only tools that have actually made a difference to my users and my mod team?
I tell my friends about this stuff, and none of them want to join. And I don't blame them. So, I hold out hope and keep working and we'll see. If things did start to improve, I 100% would start telling everyone who would listen to come here. I think the fedi is the future of social media, and I believe we'll get there one day. I just don't know if it will be anytime soon.
