I don't just want a bunch of Black instances where Black people are safe. Black instances are great and I love them, but that's only half of the solution. That's like telling Ruby Bridges that she'll be safe as long as she stays in the Black school on the Black side of town.
Instead, I want any new admin that creates a small community like "Bike Atlanta," or "Geologists dot social," to be able to welcome users of all backgrounds without being inundated by racist trolls.
