Banning of Purity Rings at Girls' School

Reading this earlier was slightly worrying. Fair enough there is the whole issue that the school could be seen as discriminating against those of a Christian faith, but that aside I think there's the bigger picture to think about. The number of teenage pregnancies in the UK is quite disturbing and even more worryingly we have girls as young as 12 giving birth. Society should really be focusing on tackling this issue and I think a lot of that should be going on in schools. What message is a school sending out to its pupils if it is banning abstinence rings? Shouldn't perhaps these girls be congratulated on choosing not to become another statistic? (Noteably I would add that perhaps they are not so much choosing as having been indoctrinated by their faith, and that they are not so much choosing for moral and informed reasons as so much that it is merely a requirement of their religion but regardless they're hopefully not going to contribute to our rising teenage pregnancy rates).
