This is my opinion too. I dont have racist parents (anymore than anyone can be said to have some degree of inherent racism we try hard to be mindful of and eliminate as we become more aware), but I did grow up around a lot of racists. I was always surprised that people I knew, even ones who had black friends and were otherwise fine towards other races, would get really weird about a white woman and a black man having some sexual relationship.
Then the guns came out and it was all kinds of horrific slurs towards the black man and the white woman both. I specifically remember the common understanding for these people was that a white woman was “ruined” beyond repair after being with a black man. Even when I was young, it just screams of an outrageous level of insecurity
And it will never not connect even when you dont want it to
