“The only “proof” of racism offered is underrepresentation in some areas and overrepresentation in others.”
There is the real problem that African Americans have far lower incomes and much higher poverty rates. The Democrats have no understanding of economics, and thus seem intent on making the problem worse, but Trump among others had good ideas to improve things.
