Thanks for your kind words. I've appreciated our conversation, on this otherwise quiet thread. 

I don't disagree about there being a violent subculture, doing great harm within many Black neighborhoods.  Cliques of undirected and disenchanted young men and boys are one of the long-standing challenges of modern societies. Where a society understands those youths to be its own children and future, it tends to take seriously the job of engaging them productively. Where societies do not regard them as their own children, it's of little consequence what happens to them. 

Good luck with Anderson's book. She has a contentious thesis, but I think she does good work assembling an historically based overview. At the very least, it may give you a more detailed sense of the sorts of things people have in mind, when they argue the merits of taking an historical view of current conditions in Black communities, as I have tried to do here.

All the best
