I feel like they're being homogenized into a BIOPOC blender of uniformity, wiping out their heritage.

They are, but for once that's not SocJus types being overtly racist while screaming about their anti-racism to cover it.

They want to erase evereybody's history so that they can implement their feudalist-pretending-to-be-socialist utopia without anybody realising just how much worse it was than everything that came before it.
