you don't have to actively say fuck those blacks let me step on them to get where I'm goin, certain forces have done that for a lot of white people, and they don't even know it. For example, when the GI's got back from WWII alot of suburban homes had been built for the soldiers, but racist practices by both the fed. government and real estate agents shunned blacks away from the new houses which they sold to the white ethnic GI's and placed the blacks in the newly erected projects. So what happens in the next generation? The sons of the Jews, Italians, Polish, Irish, Greek's, etc. have a wealth base due to the equity and so on their parents were able to secure in procuring good housing, while the blacks don't have shit cuz they live in the projects they were pushed to, and live check by check.
That's just one example, of one sector blacks face/faced institutional racism in leading to a disparity between the races, and resentment. But you didn't know that, lot of people don't know this kind of shit, you have to read and study, go to college take a special course, etc.. Because this unfair treatment is not out in the open the races drift apart, not the other way around. Because even though we might not see it we feel it.
