I have almost never met a black Dylan fan either. So? What difference does that make? Dylan was certainly a fan of a whole lot of black musicians, and some quite notable black musicians were his friends and have covered his songs. You can see some of them in concert films, like the big Dylan anniversary show. Dylan gets along great with black musicians, it seems.

Does the fact that folk music was being marketed to a predominantly white audience back then invalidate it in your eyes? Why? What difference does it make? There were some styles of music that were marketed to an almost entirely black audience at that time. So? What difference would that make either?

The ethnicity of his audience is no argument against the quality or significance of his work.

You don't find too many black hockey players either. So what? It doesn't fucking matter! (and there ARE a few of them here and there)

It's a cultural thing. How many Sikhs do you find who are rodeo riders in Oklahoma? Does it matter. No. It doesn't.
