To try to put some hard figures on this.
According to the FBI there are ~8, 400 hate crimes committed. Let’s assume that the population of criminal racists in the Black and White populations are equal. With 8, 400 crimes committed we would expect 6,300 of those charged with hate crimes would be White, and about 1, 000 of those charged to be Black with the remainder committed by other minorities. Instead the figures show that only 5, 000 are White and over 2, 000 are black. IOW on a per capita basis there are ~4 times as many criminal racists in Black communities than in White communities.
There are ~1, 200 anti-white hate crimes committed for every ~3, 000 anti Black. Or to put it another way, crimes against Whites make up about 71% of the hate crimes committed in the US. That might seem to suggest that the rate is actually based on random chance, however we need to bear in mind that 7% of the population are incapable of committing anti-white hate crimes because they are white. IOW the effective rate of hate crimes against whites is four times that committed against blacks, which again backs up the figures on perpetrators of hate crimes.
So there are the hard figures. Minorities are much more likely to be criminally racist individuals. Of course this doesn’t address which areas are most racist, but if we assume that racists are spread evenly across the population or, more likely, are in higher numbers in mono-cultural communities, then we would have to say that the most racist areas are those populated by minorities.
