I don't think you understand what people are complaining about here. The issue isn't what he's doing, it's how he's doing it.
Jokes like "don't let the neighbors see this black kid scrubbing your porch" and "who does this the most? the kids the dogs or the ugly black guys who eats fried chicken" being told to white people are pure c00nery and buffoonery. The nikka thinks he needs to shyt on his race with dumb stereotypes just to make people laugh.
He obviously has more jokes than that, but he's doing WHATEVER it takes to make that sale, even if it means stomping all over his own pride to do it. Seeing that he's dark skinned, I wouldn't be surprised if he had some self-hate issues as well since he can't seem to stop mentioning that during his shtick.
He's a great salesman, but the c00nery needs to stop.
