These laws are designed to deter adults from preying on children (i.e. exploiting their relative inexperience, immaturity, financial dependence etc.) This is a good thing.
It's weird that the Guardian tucked that at the end of the article instead of reverting them and putting the destruction of sex ed' as the main title.
Edit: many PP (now the governing party) officials are in the sect. It has a lot of influence. Also the bishops. Abortion laws projected regression is another painful example.
Anyway society is overwhelming against those measures. PP won elections because the bad economy, not that they have fixed anything. Social politics is the "tax" we have to pay.
