I think it is just fine.
This was said in a complimentary way.
No Seriously!!!
The black community endlessly refers to each other using the N word...and it is graciously accepted. A term of endearment. He may have even urged her to say it....and by his continuation of the sexual involvement..Do you think he was offended ???
Way too overblown
If she was racist..would she be doing that guy. I think not. My guess is he enjoyed the compliment and the closeness she felt in saying it.
The reason it gets no air time...Is the Black community understands this. Al Sharpton would be all over this if he thought it was racist. It was a loving ..I wanna fuck ya ....term of endearment!!!!
Nothing more. Don't read too much into it.
P.S. It is an awful term!!! I agree. But not in this context!!
