It's wrong to hit children, usually wrong to hit anyone, barring self defence or the defence of someone else, that's just common sense and good manners. Anyone who thinks they are instilling 'respect' is delusional, they are instilling fear, and that doesn't correct behaviour, that just drives that behaviour underground and breeds anger and resentment, far better surely to have a conversation with a child and make them understand why something ought not to be done? That gives them the power to alter their behaviour and is life affirming, the alternative does nothing positive whatsoever.
