One of the most absurd things I've heard is a 78 RPM record of a choir from a famous black college singing "Joshua fit de Battle ob Jerico." I HATE dialect. I was disappointed to hear what sounds like educated black men singing like white people thought black people sing. When I was a small child, I used to ask my parents why they did that. I never liked the answer. I don't think my parents did, either. I don't know that it's racist, although I can see that it is (let's make black people sound stupid and incomprehensible), but I hate dialect.

I guess that's one reason for the "folk process".
