Not by me, and I grew up in the hood.
When I first had to learn to use a computer at work my teacher was a young black guy who was from Oakland. He used to tell me stories of the horrors he went through because he applied himself early and wanted to go to college.
He was beaten and had his school work destroyed so many times that his father who was a navy vet arranged for him to go live with a former shipmate in the central valley. He said his junior and senior years were trouble free even though he was one of only a few black students in his school.
He laughed when he told me the hardest part of his adjustment was because he was not a jock. Everyone just assumed he could run a 9.5 hundred and dunk from the top of the key.
