Whatever basic values would allow them to function in society, and within the law.What do you mean by reasonable values?
I remember reading a study that linked increase teen pregnancy with a more religious population. This was in the US however. [Haven't looked at the actual data but this seems interesting].Besides societies in Britain are messed up. High teenage pregnancy rates, high crime rate, rise in promiscuity and many dysfunctional families. So yeah Secularism is excellent for society.
Central and South America and most of Africa rank near the top of crime statistics, mostly very religious areas.
[Other stuff]
If you have some real data to back up your claims I'd love to see them (honestly).
