personal experience:
Kids on my h.s. basketball team (JV) said stuff like that alot.. but the team was mostly white. They didn't grow up playing basketball with mostly black people, like I did. They were always extra-intimidated when we'd go into an "all black school" such as Ely or Dillard. I'd actually get way more playing time during those games because I could break their full court press, lol. So to me it was just normal, and I was always the rarity (because I was white) growing up. When I was younger people would call me white boy, Larry Bird, and eventually Jason Williams. lmao.
I'd just suspect that a sport that is majority x-race, athletes would mention the race of someone who is y-race.. seems common from what i've seen. Usually it's not racist, it's just some kind of distinguishing feature that somehow is used to label someone.. However, i've witness it used in racist ways.
I don't know if I ever mentioned it here, but, that kind of stuff was what actually made me not play varsity my senior year (junior year I broke my wrist). It's one of my few "life changing moments". The varsity coach was giving me a ride home after a summer league game and was criticizing the way I handle the ball. That game he benched me several times for actually driving in and scoring, or getting fouled; because I did it before we made 3 passes. Anyway, he told me straight up, no joke, right to my face in the car: "we don't play black ball here".. I was done after that. He kept asking me to try out/play, he had no idea why I wasn't. I really wish I had actually told him why I didn't care to play for him. That really bothered me & it still does today. That coach really ripped something from me, I really loved the game, but I lost alot of love for it when he hit me with that.
