I will say the most 'communal' cultures have beef issues, and african americans are more communal than white people. before you start citing mexican job figures go check how many of them have have off'd their own family over bitches and money or stabbed someone on some straight petty shit. Most people in communal cultures are annoyed by their community. People in completely individualistic cultures like white people don't have a sense of obligation to be affiliated with anyone they don't like, where as black people will remain affiliated with someone either through friendship or beef. Two white people that have 'beef' will seldom see each other again.
