you mentioned it would be bold for a Black-only community to try to exist IRL, and that's accurate - those communities even when just majority Black without exclusion policies have historically been oppressed and met with physical violence... Same with indigenous communities and so on, turns out white settler-colonial culture is intolerant and violent.
