Oops, I meant to say non-African-American minorities.
There's an entire section of the FAQ devoted to the question: How were other minorities treated during the period of racial segregation in America? Are they helpful for your question? Do they prompt any further questions, or do other people here maybe have more data to contribute?
Hey there!
I've answered this question previously here, but i'll happily answer any follow-ups to the best of my ability.
