History and current events say otherwise.
Of course, the South is used as a scapegoat and a culpability transference mechanism for others in the rest of the country to show how racist they (allegedly) are not.
I do actually agree that there is probably more racism in the South. I think probably 60% of whites are actively racist there, and in the rest of the country it’s probably 40-45%.
However, personally, the most racist statement I’ve ever heard anyone make was – check this out – in Seattle.
And I grew up in the South where I heard some truly heinous racial utterances and imprecations.
Anyway, for most white people their idea of racism seems to involve something like attempting to run over a black person with your car, while their thoughts about how black people “really are” are just the obvious truth.
That form of racism knows no boundaries, and is nearly as prevalent in the North and West as anywhere else is what I’ve found.
