That’s a silly argument. Biden (aside from being an unrepentant segregationist!) acted as an active agent of white supremacy, and Kamala would have too, just like every President has.
As an aside, it wasn’t the majority of the population. It wasn’t even the majority of the voting-eligible population. It was like a little over a quarter, I think.
White colonial ideology has historically been violently opposed to “equal rights and fair treatment,” merely proclaiming such things while devising excuses to exclude people from it. You are speaking as though the non-white savages would need to have “equal rights and fair treatment” imposed upon them by whites, which is just being a classic racist piece of shit.
“When I’m mad about orang man, I do a racism” is not a compelling excuse.
