WOW, starman...uh, maybe one or two less thermosfuls of coffee in the future, huh?
I don't see a whole lot that needed substantiating in gregjohnson's post - maybe the Elvis quote. It's been pretty well documented that (many, not all) radio programmers didn't think America was ready for a black man to be the standard bearer for rock'n'roll in the mid - 50's, as was the case with most American institutions. The U.S. military was one of the first , and most successful institutions to integrate...major league baseball, which was about 80 years old at that point, was only a decade beyond Jackie Robinson and still had relatively few black stars...and obviously it would still be many years before many other facets of American life were even
legally integrated. let alone in a practical sense.
Your Jimi Hendrix example is flawed because first of all the 60's were not the 50's...a whole decade of civil rights upheaval had been going on between Little Richard and Jimi Hendrix ( during which time Hendrix played in Little Richard's band ) and in the music world, several years of massive successes from Motown and to a lesser degree Stax had warmed people up to embracing black stars. Add to that the fact that Hendrix really did have talent and oodles of star power. And also there just hasn't been a huge number of black musicians that have tried to make it as "rock" musicians - willingly allowing and qualifying themselves to be categorized as such - so the sample is really too small to make Hendrix' rise to fame remarkable enough to make a case either way.
And did you REALLY, TRULY say that the NAACP tried to destroy "real equality based on REAL merit and not the color of someone's skin"???...oh my god

Do you know ANYTHING about American history? It's only been in roughly the second half of America's existence that America would acknowledge that certain races were any more than cattle...and only in the last 45 years that blacks could eat, drink, vote, learn, and worship as equals (in a legal if not practical sense)...in YOUR lifetime and mine all these things were denied, and some of them still are in some places.
"REAL equality" is still a work in progress in the "Land Of The Free And The Home of The Brave".
