I can believe that. Rock has come out on record saying he regrets performing that bit.
I can't tell you how much I hate the fact Chris Rock is regretting this joke. All because of "new nikkas" who weren't there in real time and white racist."black people" and "nikkas" understood the joke and it was all love. If you ever had a car or house broken into,ever been in a club that was shot up and you only live around,and are hanging around black people at the time,you probably assumed and blamed it on phantom "nikkas".
"nikkas won't let you have nice shyt

"nikkas always gotta fight and fukk up a good time

I've said these things while probably falling into the category of "nikka", as I was stealing shyt too on a technicality in my pre righteous era. The joke is not a true reflection of how you feel about "black people" or "nikkas" or meant to be divisive

Trust ,an audience full of black people would have felt uncomfortable in unison if there was a need to. That would have been felt on the special.
It was a joke that worked in its time.
