I'll agree that there's a degree of genetics at play, but I'm a strong supporter of the idea that culture drives a large portion of behavior. Have you seen what passes for black culture in the U.S.? Awful stuff, I can't imagine the state of my mind if I had been raised on that. One could argue that only a lost cause would willingly remain under the influence of a destructive culture, but I was a kid once and know there's only so much agency you can expect until a certain point in maturity is reached. More simply, no one can be expected to choose a better option unless the subject actually understands that they can choose.

It gets difficult to decipher the cultural influence web when it comes to figuring out why so many whites want to kneel, so I understand that it's an unattractive stance to a lot of people. An oversimplification is that we have multiple cultures at work that support the idea of "the strong must serve the weak".
