Ironically, liberals have arrived at the same conclusions via going the completely wrong direction.

For example, a Black student failing a test is racist (or rather "discriminatory") because Black students cannot be expected to perform like Whites. "Equity" is a valid concept because, if you want equal outcomes, you need to give Blacks and Whites different tests, reflecting their actual capabilities. Somehow, liberals have fully internalised the idea that some races (and other groups) are inherently superior to others (which is why you can't "discriminate" against straight White males; we're just the pinnacle of humanity) while simultaneously being willing to sacrifice everything to make that not true.

Their means are sane, but their motive is not. Tolerance is not a virtue and discrimination is not a sin. We should treat Blacks differently from Whites, as they clearly already do, but not because we are correcting historical injustice or some other claptrap, but because Blacks are inherently more violent, less intelligent, and unable to operate at the level of Whites. Blacks had better lives under Jim Crow than they do today because those laws protected them (and us) from themselves.
