Your framing is dishonest or you legitimately are incapable of properly understanding someone's clearly articulated point.
A system, that has hundreds of years of existence that we have direct evidence of, did not magically disappear. The burden of proof is on YOU if you are going to make the claim that a deeply entrenched system that lasted for hundreds of years magically disappeared into thin air. Is that the claim youre making?
It didn't magically disappear.
It took a civil war and then another 100 years for the civil right act of 1964, which is 56 years ago.
You're not not providing proof that the system is racist.
