Everybody is a little bit racist, and you're right, it will take many more generations for that to be turned off. It's not really that everyone is a little bit racist to a point where everyone is a little bit actively discriminatory, since the concept of "race" is a social construct to begin with. It's really more of a "groupism" thing. Or, more accurately, a "tribalism" thing.
Humans are inherently tribal. We are biased towards people we feel are like us and against outsiders. What constitutes an outsider differs from person to person. It often coincides at least partly with race, because "looks different from me" is such a clear sign. But for an individual person, race might not matter as much as other things.
Research on the unconscious evaluations that people make instantaneously about others based on race - known as "implicit bias" - has been well established for decades. But at a more fundamental level, this implicit bias applies to groups in general (pick any distinct group - race, religion, cultural, economic class, fans of sports teams, etc.). Poor whites and poor blacks have much more in common with each other than they do with rich people of any color. Integrated sports teams, where jersey color can trump skin color (just watch a brawl between one racially integrated sports team and another) is a good example. And as this most recent presidential election with regard to the voting patterns of Electoral vote versus the Popular vote makes crystal clear, a white New Yorker, for example. will have more in common with and feel more comfortable around black New Yorkers than white rural people. That's still tribalism, still groupism, it just happens not to be based on skin color. Race is simply a subset of groupism/tribalsim.
Black liberals refer to Steve Harvey, Kanye West, even MLK III, as "sellouts" and "house niggahs" because they met with Trump.
So when people make near-instantaneous judgments (implicit bias) about others based on skin color or some other groupism thing, that doesn't in and of itself make them bad people for doing so. It's what they do with that implicit bias, how they react to it that matters. When police instantly assume you're up to no good based on your skin color, that's a problem. When you refuse to serve someone in a restaurant, or rent them an apartment or sell them a house,based on skin color or some other subset of groupism, that's a problem. When black liberals refer to Steve Harvey, Kanye West, even MLK III, as "sellouts" and "house niggahs" because they met with Trump, that's a problem.
