There are plenty of people who don't like r&b and certainly don't like the modern iterations. Black people are not a monolith. There are more black people who can't stand Teddy Riley/Babyface/New Jack/etc r&b than those who love it. Go ask a 60 year old black woman if she likes that shyt and she'll probably laugh in your face and tell you Motown/MJ/Luther/Anita/etc are real r&b, not that raunchy shyt from people who can't sing.
Back to Peter tho. I'm starting to get tired of these conversations because I sense that Rosenberg thrives on this shyt. Not just the attention, but the idea that people hate on him. It's that little man syndrome shyt. A bald, overweight, short dude who was NEVER apart of the cool club, yet loves trying to shyt on the cool club with his pure "real hip hop yall" opinions. And when he goes too far (Chuck D, Combat Jack, etc) he gets to pull the "I'm just a dumb white guy, I don't know these things sorry" card and gets away with it. I'm tired of it man.
