Is it disproportionate to the general population?
Even if so, the impetus or the result are not due to any white-ID culture. Black crime largely reflects the results of black-centric culture. Two very different dynamics.
As I understand it, the population of serial killers and mass murders in the US is almost exclusively white. OF course there are exceptions, and outside the US there are other populations that have the same and few are white, but in the US it is almost exclusively white.
Maybe there is some kind of mental dynamic in play that has a strong preference for members of the majority race?
Hell I cant explain it.
