Is the governments (UK) new advert proof that parents are failing their children?

The UK government has today launched an advertising campaign attempting to highlight & cut down the amount of violence perpetrated by young men against their girlfriends. Apparently a quarter of girls aged 13 to 17 had experienced physical violence from a boyfriend and a third had been pressured into sexual acts they did not want. What are British parents doing wrong? Why are we breeding a degenerate generation who thinks this is appropriate behaviour? Who is failing these children?
