Possibly the most unsettling aspect about religion for me, is how it seeks to forcibly impose it's beliefs onto little children.
All around the world, respective cultures with their respective deities, and their respective belief in being the exclusive truth, nominate children from birth, as belonging to their faith.
They are forced to accept ludicrous teachings well before the age where they can possibly reason for themselves, in the hope that this fantasy becomes so deeply entrenched in their psyche that it will over ride any rational analysis of the validity of what they have been taught, but simply retain it as unquestionable truth, which is what they are told since birth.
Surely the christian seeing a child sent to a madrassa to learn nothing but the koran, would see the unfairness to the child in that circumstance.
Is it so hard for them to even contemplate being happy to primarily seek to see all children given the chance to learn to think rationally, and to be able to reason for themselves, before attempting to force they make a spiritual decision that surely should be everyone's right to make for themselves, rather than something you just inherit from your family and culture.
If christians do not face this question soon, they could well find themselves in cultures where their beliefs are simply being outbred by another.
Modern secular societies really need to make the first move, and start by separating schools and education in general, from all religious proselytising of any kind.
If it is left up to who can breed the fastest becomes the world's dominant religion, then god help us all.
