I've observed many parents being bullied by their children recently! I certainly wouldn't say that many parents in UK are totally in control of their offspring. But I agree there are a few cruel and repressive adults around who may bully children. I would say that most bullying comes from peers, at school, in the street and online. And from 'colleagues' at work. In comparison, parental bullying isn't as common. But that's just a personal opinion, not backed up with data.
