From the '60s onward Democrats set out to destroy the black family unit (and they've largely succeeded) in order to mentally re-enslave black people into believing they're unable to survive without the tax-funded largesse granted them by their Democrat plantation owners. They've largely succeeded at that, too. Lots of brave black folks have caught on to the Democrat's scam but are immediately denounced and un-personned if they dare speak up...Uncle Toms, Oreos, etc.
We have two options as to why this happened:
1. Democrats truly are racists with an abominably low view of black people and sought to exploit them because they're racists.
2. Democrats aren't really racist but have merely fooled black people into selling themselves into a perpetual Leftist voting block in order to maintain Democrat power and feed Democrat causes (the multi-generational welfare state, the abortion industry, the drug trade, etc).
Now either way you view it, AT THE VERY LEAST Democrats are evil, cynical, lying hypocrites who've exploited and destroyed black people in their pursuit of power and money...which is indistinguishable from what would happen if Democrats were actual racists.
Point is, even if Democrats really aren't racists, for over 50 years they have behaved exactly as vile racists would behave. Even if they don't hate black people for the reasons racists would, Democrats demonstrably despise black people and have nothing but contempt for them, as proved by what they've done to black families.
