I agree with you, the gangsta-thug subculture now reaches across all ethnic boundaries. Like one poster commented the other day, it’s like killer bees invading a normal hive colony and taking over all their behavior.
It’s not strictly an urban problem anymore, either. I live in the suburbs and the influence among minorities here is astronomical.
Similar to Islam, it is simply an ideology/culture that justifies the most base human nature of antipathy to every one of God’s commands.
