Of course it's about race. If a group of people that look the same, speak the same, act the same (you know, a culture) and that live in the same place for virtually their entire lives encounter an outsider, they're going to react negatively. That's precisely why I will never again stop in Northeastern Oregon.
Judging from what the nurse who came to his rescue said, the neighborhood is full of trash. People with no direction and no pride. Just the kind of people you can expect to react out of malice instead of reason. It's only bigoted unless you attribute their behavior to all black people everywhere.
Rcade, I dont like to criticize people in their own place, but you need to wake up. Overtures are often not taken to heart, but taken advantage of. Theres enlightenment, and then there's just being soft.
