There is a difference and a history , from the comedians in the 70s like Redd Fox, Richard Pryor, and Paul Mooney. To the early days of rap and hip hop. Just because you can't see a difference doesn't mean there isn't one.
You asked what people felt, I replied. Let me clarify: I can see how other people (specifically black people) might have a difference in their minds... even many of them. And, I've heard the Fox, Pryor, and Mooney routines. I've also heard Eddie Griffin, Katt Williams, and other comedians' who are too innumerable for me to name or remember routines that cover the same ground. I've heard less of the rap and hip hop. I've heard some of it, but I'm more of an R&B person. The only hip-hop I really enjoy is the really
angry shit... probably because I used to be a headbanger and poor so I can relate to the rage.
Anyway, I'm digressing. Back on topic: I see how other people can see there's a difference, but
for me, there's not much of one. If a black guy starts saying about someone who isn't himself in a negative context, I'll probably sigh a little bit on the inside and feel the guy is a bit goofy, but I'm not gonna say anything. It's his choice. As I noted above, I do this about my own folks, and I definitely admit that I'm goofy. If a white guy says it, even in the "a" form, unless it's at a KKK rally that somehow I walked in and I know I'm otherwise gonna die, I'm pretty sure I'm gonna tell him he needs to keep that shit to himself. I don't care if his biggest, blackest friends gave him a pressed platinum card that says "Nigga Authorization". If they want to stand up and defend him and say, "dude, it's really ok", then ok, I guess, but he isn't gonna be my friend anytime soon, because I'm all full up on crazy over here.
I'm happy to be called prejudiced, racist, or whatever for having that attitude, or even be told "your defense isn't needed, we'll take care of it ourselves, so back off". That's fine, but I'm not doing that on behalf of black people. I'm doing that on behalf of myself, because I don't need to hear that shit. I don't want to hear that shit. I grew up around that shit. Beyond the realm of comedy or entertainment, where it's just going to be a feature in the acts of people I like, I think it's something that I can take out of my life.
