When I lived there it was Northern and Southern High Schools. And racism ran deep. I attended an Independent Baptist church and it was all white. We were instructed that if we went on visitation and cold called a house and the inhabitants were black, we were to say we had knocked on the wrong door. I hope things have changed there as well. They may have - I am just stating what actually happened to me. My folks let me know that this was NOT right as far as they were concerned. But they didn't know what to do. We had a boy who lived down the street from us who my brothers played with and he was black. You could have heard a pin drop when we walked into VBS with him in tow. It was like living in the 60s. Un-real.
I grew up and went to Jordan High School ('84) and things have changed. Race isn't the issue in most cases, that was the Old South. The New South, is about one thing and only one thing, money.
There are bad people everywhere, but I wouldn't call Durham a hot bed of racism.
