The social scientist Charles Murray wrote a book a few years ago called Facing Reality: Two Truths About Race In America:
The charges of systemic racism and White privilege that are tearing the country apart float free of reality. Two known truths, long since documented beyond reasonable doubt, need to be acknowledged and incorporated into the ways we approach public policy: American Whites, Blacks, Latinos, and Asians have different rates of violent crime and different means and distributions of cognitive ability. These two truths drive the problems in policing, education, and the workplace that are now ascribed to systemic racism. Facing Reality lays out the evidence clinically and in detail, without apologies or animus.
Murray mentioned four major races there, but America's racial problem chiefly relates to blacks. Blacks have the highest violent crime rate, by far (about 10x the white rate), and they are also, on average, the least intelligent. There are of course brilliant and law-abiding blacks, and dumb and violent whites, but decades of objective data don't lie. You are more likely to be killed by someone who looks like Karmelo Anthony than someone who looks like the young man he killed, Austin Metcalf. And you're statistically safer having an air traffic controller or surgeon who looks more like Metcalf than Anthony.
