Non-sequitur.
I'm sure some people are as you say, but what does that have to do with the post you quoted?
Are you perhaps suggesting that rap (which btw I do not like) and hip hop (some of which btw I quite like) would only be excluded from the RnR HoF due to African-American bigotry rather than because the rap and hip hop artists/groups don't do any RnR songs?
In case that is what you are suggesting, please note:
(not all-inclusive) INDUCTEES:
The non sequiter is you listing black inductees to the Rock and Roll Hall of Fame when nobody in this thread has suggested the Hall of Fame is racist. They inducted Grandmaster Flash, so obviously they don't share the very narrow views about music expressed by many in this thread.
I happen to think cheesy hair metal like Quiet Riot, Poison, Twisted Sister etc. is some of the dumbest, shittiest music ever recorded. But I'm not going to argue that it's not actually music. Or to take an example from earlier in the thread, Twilight may suck, but no sensible person would deny it's actually a book.
