While I agree with the point about uniting against capitalism, this makes white power and Black power seem like equal terms and ideas.
They are absolutely not.
Placing them on equal footings is a red flashing warning beacon to those who do face racism (and others who are marginalised), that their struggles aren't seen (or at the very least minimised and set aside "for a more convenient season")
I took it more as illustrating that white power as a concept in modern times is a tool being used to divide the workers. The elites don’t mind “diversity” amongst themselves if it doesn’t impact the bottom line.
All they need is a underclass that can be controlled. If they can get the poorest among us to fight for white/black power then there’s less energy to focus on how those with capital keep both groups oppressed.
To those at the top, it’s not usually about racial superiority. It’s simply because in our society, maintaining an exploitable underclass is convenient and keeps the cash flowing.
The most zealous bigot will always be part of the lower class, intentionally deprived of knowledge by those above them to ensure they keep this useless fight going to distract from real solidarity.
