Just a white chick with a bizarre argument about cohabitation. We have the evidence on cohabitation, it is inferior to marriage in every way on childhood outcomes.

And even if we find it a step above the worst case scenario (ie no father), blacks again lead the racial groups in that: https://ifstudies.org/blog/race-cohabitation-and-childrens-family-stability

And anyone that wants to play the slavery game needs to explain why the black family was stronger than whites pre-welfare state. You literally would have to believe that the worst kind of racism in history failed to dent the family structure, but 1960s and 70s racism did.
