You should become more knowledgeable of The Great Society, and the welfare components of it. But even if you disregard that. The fact that almost 8 out of 10 Black children grow up with only one parent puts them significantly behind. Much more so than any residue of racism that exists here and there in society.
Imagine being so pig ignorant and racist that you don't think the rates of single-parent households in Black communities is connected to racism AND that any racism left is "residual". Just astonishing levels of stupidity on display.
