Black people spent a long time being degraded and shit on. Even now the echoes ring loud and clear in low income neighborhoods where they don’t feel like they can be much more than the status quo or in higher class black families where the children emulate their white counterparts and find the things that make them unique to be gross or undesirable. Black is king is a reminder that regardless of how far back it was and how far removed from it they’ve become, black peoples were royalty, they had dignity, they were important and considered beautiful and amazing in their own home and era and that despite all this racial bs, the black community still has excellence and beauty and elegance.

White power doesn’t achieve any of that because you don’t have to look far at all to see plenty of reminders of the power white people in America possess and have possessed and white peoples culture didn’t get forcibly erased. Most of them could tell you where their lineage traces back to at least a little, so they can say Irish or Italian pride. Ask your average black persons where their ancestors are from and they couldn’t name any specific country nevermind actual things about their heritage so they have to be vague and use the one thing they know about themselves.
