One of my white attorney friends, male, is married to a black lady. Her kids are mixed race and she went around with them in the shopping cart. She also got stopped for driving while black in our (mostly) white suburb.
I grew up in Rochester, New York in the 50's. Went to a racially-mixed high school, and graduated in 1965. The school was in the black section of the city, and we never had the fights or problems that occur in today's schools. Most of the black kids I went to school with were academic achievers. Had better marks than me. Some were in the honor society. Our senior class President was black. The Valedictorian of our graduating class was black. The head cheerleader was black. I was the co-head cheer leader, and we worked well together. I don't know what happened to schools over the years. They have been nothing but a hot-bed and breeding grounds for trouble. I'm glad my kids never gave me grandchildren, because in today's world, I would have worried myself to death over them.
