You can't say it's ok for someone who's black to say it to downplay it's significance but nobody else. That's not how it works. Truth be told I hear white teenagers using it in that exact form all the time. Turning it from a slur into a generalized term to refer to one another. It annoys the crap outta me personaly. Point is you can't have it both ways. I apologize as a gamer if you were subject to abuse for your race but you have to take the high road brush it off and know in your own mind you're smarter and better than any bigot who thinks skin color defines a person.
