Of course you find many Southern whites who are extremely kind to all.The Southern Hospitality phrase is based on substance.
Yet my job and volunteer work back in the Seventies put me in a lot of situations where I would be the only white guy in a mostly black environment.Most whites would stare at me and wonder"why is HE with HER,HIM or THEM."Once in a while someone would ask me if I was their"priest"or "teacher".
Blacks would also give me some strange looks yet seemed more accepting when they found out my intentions were benign.
Maybe things have changed now.I still prefer the racial atmosphere in the South to that of what exists now in California where mixed friendships are pretty rare.
Strange. I would say SoCal is the most interacially mixed state I have ever been in. I am curious as to how old you are?
So do I, though I have only experienced it when I travel. I love the South, and when I retire (many years from now) it will be to GA or the Carolinas.
It sounds to me as if it's you who has the problem.
