If I understand your response correctly, you’re asking what good is figuring out the “why” if the result is still the same, that the “why” doesn’t matter if it doesn’t do anything to stop the racism against Blacks. Please correct me if that’s not what you mean.
Thing is, the “why” is all-important. We can’t truly change our ways until we figure out why we were that way beforehand. I know my replies tend to be long, so please be patient with me.
I grew up racist, and it took me a long time to realize that my whole family and every White I knew in the Delta were racist. The important point, though, is that almost without exception, not a single White I knew held malice against Blacks. We really wanted to see Blacks become successful…but none of us could see that it was our own conduct and untoward assumptions that was (and still is) preventing most Blacks in the Delta from rising above poverty.
Please understand the main point: most racists don’t even know they’re racist at all. They think the only real racists are the idiots wearing hoods, and that they themselves can’t be racist since they don’t hold any hatred or malice towards other races. They don’t realize that their own non-malicious assumptions are all that’s required for racism, for those assumptions inform the effectively-racist social and political policies.
The second point is that when I began to recognize my own racism for what it was, I began to see that yes, in America, Whites are by far the most racist. I’d seen more than a few times the accusation that all Whites are racist, or that only Whites are racist, and it seemed that those making such accusations did not themselves realize that accusing an entire race of being racist (or of being the only racists) is itself a racist accusation. After all, if all races and cultures should be considered equally worthy of dignity and respect, then it stands to reason that all races and cultures are equally capable of great wrongs, including racism.
So if all races and cultures are equally capable of great wrongs, how can one explain why Whites commit by far the most (and most egregious) acts of racism in America? That is the root of the sociological rule you responded to. I’ve seen the same thing in every nation I’ve traveled to around the world — whichever race, culture, or religion is on top is the one that will commit the most (and most egregious) acts of prejudice.
So to answer your question, does any of this reasoning or understanding help Blacks at all? No…and yes. It doesn’t help because it simply means that as long as Whites are on top in America, Blacks will face an intolerable degree of racism…
…but it may help in that when Whites are shown that racism doesn’t require malice, that they as individuals (and as a race) are not being accused of being evil, horrible people, but simply that while they think they mean well, they don’t realize how racist their actions are in reality, more of them may be willing to accept the reality of their own racism and white privilege, and more willing to do what’s necessary to correct their actions.
Lastly, there really is some hope. Whites are still socioeconomically-dominant in America, but in a few decades, this won’t be the case. Our dominance is gradually and irrevocably diminishing. It’s not just in America, either, but in much of Europe. Does that realization help you today? No. But as I demonstrate in that article, while this “race war” that Whites have been waging on Blacks for the past 500 years won’t end in my lifetime or yours, Whites have lost the war. There are many, many battles left to fight, many or most of which Whites will win, but white supremacists have lost the race war — when our grandchildren are old enough to have grandkids of their own, they will live in an America where Whites are no longer socioeconomically dominant. Short of some kind of nationwide or worldwide catastrophe, this is a demographic certainty.
I hope this helps.
