"Are American institutions racist? I honestly dont know. What do you mean by institutions though?"
I mean things like the police, army, political establishments, judiciary, academia.
I would think they'd all have varying degrees of racism and breadth of diversity in them. The police seem to be a deeply racist organisation, simply based on the number of back bodies they seem to be piling up on the sidewalk.
This is an obvious (to me anyway) institutional failure to see non-white people as real citizens.
I don't know if diversity courses (or similar) stop the kind of conversations you're wanting to have? It's about tolerance usually, not acceptance?
