After looking at the lyrics again, it does seem to say that he is not talking about the Holocaust.

Thanks for clearing that up.

"I'm not an okayplayer, I just b*tch alot."

"the rap universe is big enough to hold both Will Smith, Ja Rule and Common".

"Rap's a funny business, really. People will pay to experience as "entertainment" what in real life they'd run a mile from: bug-eyed sociopaths threatening cruel and unusual deaths, nouveau riche bores bragging about their income and expensive possessions . . . And let's not forget the underground: paranoid poets who've never met a conspiracy theory they didn't embrace, autodidact crackpots who've glimpsed the secret of the cosmos in a cloud of weedsmoke—the sort of I-be-the-prophet spiel you can get for free if you hang out on the subway long enough." - The Village Voice
