I have two sons, now in their early 20's, who grew up without a male role model, and it's been damn hard. I watched them struggle throughout their teens and had to deal with behaviour I never anticipated and was ill equipped to deal with.
I made a very stupid mistake in my early 20's and married a man who was just appalling at fatherhood and became a violent alcoholic within a year of the birth of our first child. I eventually found the wit and strength to leave when my kids were 6 and 7.
With no close family, where do you find a male role model? It's not as if you can buy one. Yes, I had/have male friends but the one who actually had any understanding of the kind of consistent male presence boys need in their lives died tragically and prematurely. Others were happy enough to participate up to a point - as long as it was fun - but when the going got tough... well, it seems like it takes a real man to stand up and be a real man.
Mothers continue to be an easy target, and I agree that mothers have a role, but I also think there's some kind of collective responsibility for childrearing that we (as a society) tend to shirk. If it's not our child, it's not our problem, or is it?
It's easy enough to expect the government to deal with it, through various agencies and education, but I reckon we have the government we deserve, and that the real issues are much more deeply seated.
Kids are kids, and far too many of our kids are vulnerable and exposed and ill-prepared for adulthood - gangs offer the teenage boy something valuable beyond words - a sense of belonging and community and loyalty that is lacking elsewhere.
There's an african saying, if you do not initiate the young men, they will burn the village down, just for the warmth.
