DougR, I suggest you read the article that was linked to in the opening post of this thread. That will set some of your misconceptions straight, as well as answering some of your questions.

BTW, there was no "Blacks only" prom. There was a "White's only" prom and a "Mixed" prom where everyone was welcome.

I notice, though, that you don't read my posts, so I don't expect you to see this one.
