White supremacy still operates as an active form of conquest, even centuries later, and these white defensive responses are, as you point out, part of the Macchiavellian deception involved in conquest. Too bad it is generally absent moral behavior.
The sad part is that these behaviors, which reflect active conquest, still exist literally half an era after the invention of race. I always wonder why this form of behavior still exists, and my conclusion is that the lack of stamina which results from privilege is so long-standing that, if whites were to give their privilege away sincerely, most of them would have no idea how to survive. The advantage is just much too significant. In the words of Jimi Hendrix, ‘that old jellyfish been floatin’ so long and so slack…ain’t got a bone in his jelly back.’ The same privilege which made it so easy for white people has also created a context in which that ease has eroded true ability.
So, in order to buffer this reality, they must resort to the past assertions of Manifest Destiny and inborn superiority to compensate for a more and more obvious context in which the performance is simply inferior. This is more white supremacy, at least in a presumptive context of ‘equality;’ to give the prize to the intrinsic winners, in other words, would cause a significant shift in society such that whites as a group would no longer dominate.
This causes the reactions: a continued adherence to conquest, and the fundamental lack of moral motivation which would allow for equality, because real equality would nearly guarantee that whites lose real power and, given the performative abilities of a wide range of POC, would likely lose a lot of it.
