"I can tell you that the Church's teachings on sex education etc have NOTHING to do with silence, darkness, fear etc.."
Let's cut to the point, does the Catholic Church believe that Sex Education should be taught in schools?
It certainly appears that that is what it believes, and your comments about in children's own homes certainly seems to support that.
In particular we're seeing at the moment a big struggle in the Philippines where the Catholic Church is fighting against the introduction of proper sex education in schools (e.g. www.bbc.co.uk/news/world-asia-pacific-10552591).
So to me that is "silence", they want information to be withheld.
If the Church were able to extinguish the flame of knowledge in this country to a similar degree that they have achieved in Africa then we'll see more statements from Bishops claiming that AIDS can permeate through a condom or that condoms are deliberately infected with AIDS. There's your "darkness" and "fear" for you.
And how can parents who weren't educated about sex teach their children about it? It's the blind leading the blind.
And it's not just to children, the Catholic Church also want to deny adults information about contraception and even contraception itself.
I have no problem with children being taught about abstinence.
However those that favour abstinence seem to have clear problems with children being taught about other aspects of sex, contraception and health.
"behold the statics show it is ineffective..in fact it has made the situation worse."
No they don't.
Europe has a far more open attitude to sex and it's education than we do and has a lower rate of teenage pregnancy than we do.
It's quite clearly not about the sex education alone.
But let's not stop that getting in the way of the spread of knowledge and information that will help save the lives of our children.
