There's not an awful lot we can do about how families influence their children, and a good thing too. No-one has the monopoly on what's the right thing to do. We can hope that a well-educated populace will generally try to do their kids justice. Schools have a big part to play. That does not mean that we can't have an opinion about what goes on. Unsentimental discussion, from the hip, can play a significant part in persuading parents to give more consideration as to what is influencing their children, and how. It's not about being prescriptive (I'll leave that to big religion). It's about being alert and caring. And wanting your kids to grow up free-thinking and fair-minded. You won't get that by giving them shackles to wear.
