Racist & their black blood.,
As much as white hating liberals love to rewrite history, none of what you said is true on average.
4.5% of the US population at the time did not own slaves as you claim. It was closer to 1.6%, including some black slave owners.
No, white slave owners did not have sex with their black slaves very often. No, white non slave owners did not have sex with black slaves very often. The black slaves usually had sex with other black slaves, producing black offspring. This is a liberal Hollywood attempt to promote cultural Marxism and denigrate the current White population.
The average "african American" that was a product of miscegenation most likely had sex with other blacks at adulthood, thus giving them mostly African blood. Whites then, as Whites do now, reject nonwhite mates at rates making those that do commit miscegenation a very small minority.
All races reject half breeds at a much higher rate than if it were a pure blood.
The average White American is a pure bred, at least for the past tens of thousands of years, of White European descent. Your recent media reference to 1 case of a "white supremacist" being part African is anecdotal and ignores the vast majority.
