What was race relations like in the 90s?

All I can share is my own experience. I worked a job in a large retail store and it was mostly all black and white ppl. I would say at about a 50/50 split. We had a wonderful team of workers that got on better than fine. We were all on the younger side late teens and early 20’s. I was guided into black culture by my peers. We enjoyed talking about movies and music and fashion. I closely befriended several of my black peers, we were all equal and friendship our common bond. I took a trip down to the city with one of them to place I would not normally be in and bought some Fila sneakers when they first came out. It was the only place to get them. I loved all of them and still have very fond memories of them decades later. It was one of the best seasons in my life. I even dated a lovely black girl who was a cashier. Racialism was not even a thought for me nor did it seem to be for them. I have considered this experience many times over the years and thought what changed? IMHO, This was a time when rap was in its golden age, Run DMC was huge. Everybody loved it black and white. But then hardcore rap came along which was much less mainstream. For instance NWA’s style rap and an album called Fear of a Black Planet. Just the title is devisive. There was a major shift towards this more aggressive style rap that was totally devisive. And so it goes.

I remember watching the sentencing of the OJ trial in the school library. All of the black people cheered and all of the white people booed. It was the first time I really noticed race as a significant issue. There was a lot of racial separatism in school, black and white people mostly kept to their own race. There was a significant divide in the poverty level as well.
