What I've noticed, especially when you are young is what white boys will test the racial jokes waters to see if you will let them make racial jokes so they can eventually have you accept it to be included if you are the only black person.
Gotta nip that stuff in the bud. I didn't even hear the n word in my own home growing up, I wasn't about to hear it from white boys .The reboot of Fresh Prince, Carlton was allowing his white friend to say racial shyt.
Sometimes its the other way around. A white boy in a black group is alowed to say "n*gga" . There is a white Hoover Gangsta that has a youtube channel. Was adopted deep in the hood. His set let him use it and in prison he got checked.
Many if not most of these white boys who date hard core swirlers/divestors will often if not usually use "n*gga" to see if she will accept it as a requirement to being with him. That happens a lot. I am guessing its a given. Sadly, many brothers who date white girls even encourage it privately, I've heard shockingly enough to show her he's inclusive.
Or a white girl may try it with a black guy to see if he'll accept it in exchange for access to the coochie
It's all sad .
