I may disagree with the guy in many ways, but that's a fine quote.
"White power" is a call for supremacy. "Black power" is a call for equity and solidarity.
Conflating the two by saying that blocking both or allowing both would be "equality" is.. Mind you, I've only been awake for half an hour; but it's definitely the worst take I have read so far today.
abstractbarista's comment is a political attack along the same lines. By drawing an equivalence between the phrases "white power" and "black power", there is the implicit statement that the two are morally equivalent, which is by no means the case. They then follow-up by saying that since the two are equivalent, they should be treated the same. It's a bait and switch, where the syntactic similarity is used to imply semantic similarity where no such semantic similarity exists.
