Rok, I'm going to write a long thesis that will explain strange behavior. First, what I call "strange", is not strange to the inhabitants of that particular community, be it the projects on the West Side of Chicago, the Bronx, or New Orleans
This has nothing to do with race, but everything to do with "culture". Wherever you go, people have a unique culture that explains their behavior; the weird thing is the fact that this "culture" is carried down from generation to generation, which makes it quite normal.
Maybe that explains why people who were born in New Orleans, only feel comfortable in New Orleans.
