ideally, schools should teach all religions equally, also agnosticism, and people can make up there own minds, also why should everyone believe in one religion, the true teachings of all religions allow peaceful integration between all faiths, as spain did for many years after the inquisition.
I think most western countries, england in particular, have a problem with any religion they would call extreme, the decline in nuns and priests confirms that this is not just relating to eastern religions.
For the record, I was brought up a catholic, and I think the religious education in catholic schools is very blinkered (or at least it was when I was at school, a long time ago!) but I'm now agnostic, saying that I love Christmas!
Also, I have met heavy drinking, drug using, wife beating, misogonyst, thieving, violent hypocrites of all religions, no religion can stamp out that lot.
