OK, I have an easy riddle for you. What starts with N and ends to R and that you would never call a black man one? Neighbor!
I was under the impression jokes were supposed to be funny.  It shouldn't be an excuse to normalize a racial slur.
No. I am pretty sure the word is a synonym for person living in the neighborhood or in proximity to you.
You shouldn't judge someone based on the color of their skin. It doesn't matter if they are black. They could still be a great neighbor.
But they would still be an N-word.
It's flat out wrong to use racial slurs against you neighbors and anyone else. Imagine if you moved into a black neighborhood and your neighbors called your kids with some racially offensive terms.
