I'm not entirely convinced that comparisons between religion and alcohol are relevant or productive.. As far as I'm concerned, children should be protected from both, and neither should be supported by the education system at all. That aside, one of the most important things a child can learn is the difference between fact and opinion. I was lucky, in that I seemed to work it out for myself at a very early age and my upbringing was not oppressive in any way. A great many children are not that lucky.
