True. After my last post I started thinking about these cultural variations within ethnic groups. It's a big, complicated subject.Absolutely, however .... culture can vary significantly within ethnic groups. I would venture to say where a particular person sits on the socioeconomic scale will be of a much greater impact than any shared culture.
Many people seem to deny to deny that these differences exist. Yet, if gang behavior is considered, for instance, it is easy to see how that behavior is strongly influenced by the culture found in prisons. And that culture of violence is widespread in low income areas, where many gangs, thieves, drug users and abusers, etc., are also found.
Sadly, aspects of such negative belief systems manage to spread rather widely within some groups.
