Everyone has a different defintion of wanna-be gangsters. Seems like many here are taking it these guys were black. Maybe they were, but this nonsense is cross-ethnic. The white kids are actually worse imo, as their only gang affiliation is they all have Abercrombie & Fitch credit cards.
My gf lives in an area without many gym choices. While her place is rural, I'm 10 minutes from a gym that I use that is more rec center. Great equipment, but probably 85% black because they have a number of basketball courts that are heavily used. No problems. I worry about myself, mind my own business, and even play a lot of basketball where it's physical, but not dirty. You don't go calling hand checks for fouls, but otherwise I play my short white guy game and rebound by Barkely-style lower body hip leverage, pass, and shoot 3's.
I occasionally catch a little shit, but no matter where I'm at, I expect young and dumb to go together. I actually get more annoyed at someone old enough to know better. Those guys get my temper. Young guys, I kind of just laugh off, but occasionally if they are acting the fool, I'll wait until the strongest of the group gets done benching (they only bench and curl) and then respectfully ask if they are done and then warm-up with their 205 max for about 30 reps as their friends mock the "strong" one for screaming as he 1 repped it. That usually ends any friction. Kids are sheep, they follow one alpha around and act tough, always have, always will. Many don't have a father to slap them upside the head when it gets too big. At least I did, and learned better before I caught an ass whooping. Everything comes around in life. If a kid is a true punk, he'll end up as a chalk outline soon enough. My life is too good so I won't be the one to put him there.
