your parents probably don'[t want you to get involved where you are now, because they're afraid for your safety and that of the rest of your family and friends. I would still step in and intervene if you know something is going down. How could you live with yourself if you didn't? You'd always feel sad and regret it. Sometimes you have to put yourself on the line, for others. It's the right thing to do.
Where the hell is that neighborhood? Get Out Now!!!
Just turn away, you'll get new friends, and your parents just want to protect you.
