Well, good to see that this little shin-dig is still doing, and that the OP continues to stumble along blindly. Hey, Gadarene, did you like those in-depth and illuminating responses to your questions? I’m generally not one to say “i told you so,” but… 
Thanks for the statistical analysis, Dead Badger. If anyone’s interested, i actually found the report upon which Razorsharp’s Dr Williams based his analysis. As far as i can tell, he got his figures on page 41 of this pdf file, in the section “Percent distribution of single-offender victimizations, based on race of victims, by type of crime and perceived race of offender”.
Disaggregating the numbers, i arrive at a figure of 1,276,030 interracial crimes of violence involving whites and blacks, which is the same number the good doctor gives. When he says that about 90% of these interracial crimes were committed by blacks on whites, and about 10% by whites on blacks, he is about right. The actual figures that i arrive at are:
Black on white: 1,140,670 (89.39%)
White on black: 135,360 (10.61%)
What he ignores is some of the other figures that you can glean from that page, to wit:
-
When a black person commits a crime of violence, there is a 56.32% chance that the victim will be white, and a 43.86% chance that the victim will be black.
-
When a white person is the victim of a crime of violence, there is a 72.9% chance that the offender will be white, and a 16.7% chance that the offender will be black (numbers don’t add to up to 100% because of other races, and unknown races).
Now, none of these figures tell us a great deal by themselves, but they certainly provide some room for doubting that there’s some massively under-reported epidemic of black-on-white violence.
For example, paragraph (1) shows that, despite the overwhelming predominance of whites in America, black criminals still choose white victims almost as often as they choose black ones. Obviously this has much to do with simple proximity, as we have all been suggesting in this thread. But if black-on-white hate crimes were the huge issue that Razorsharp makes out, surely all those evil blacks would be actively hunting down a much larger proportion of white people than they currently are.
And, as paragraph (2) shows, if white people are worried about the level of violent crime that they suffer, then the first place they ought to look is among people of their own color, because they’re much more likely to be a victim of a white person than they are of a black person.
As for Lib’s question, according to this report from the 2000 Census, people who identify as only white make up 75.1 percent of the US population, and men make up 49.1 percent of whites, which means that white men make up 36.9 percent of the US population.
Even if we include people who define themselves as white in combination with another race, white men still only make up 37.8 percent of the US population.
