We still have all-white casts in various forms of fiction, and the hard core viewers never bats an eye. Let's not even mention the outrage when a POC is added to a traditionally all-white cast, or when race-bending is involved. Yet, here in a fantasy thread about an all-black cast, where folks are just throwing ideals about (woefully under-utilized characters), others want to raise their eyebrows, and think segregation.
So much funny stuff.
