I had the opposite experience but with the same good outcome as you. I was a white kid in the 80s who moved from an all-white school (I think there was one black kid in the entire school) to a suburban school that would have been all-white but it bussed in kids from the inner city. I know that added exposure helped me break out of the cycle of racism I realized later was so prevalent at my earlier school. It’s almost like having experience with something helps you understand it better… wild concept.
