Religion - genuine belief or educated to believe

Simple question is a religious belief a choice or simply tought as the right thing to think.if I am brought up as a chritian then i belive in cristianity, if iam brought up as a Hindu iam a Hindu.If i am tought to think for myself but given the facts do i have religious faith at all?My children are tought in a cristian school but given facts of many religions. but i dout they will become anything else that chritian if any.But they belive what there teacher tells them as fact.

I think you are right about some people changing from one brand of christianity to another and that it is rare for somone to have a complete switch to a very differant religion.
But if all beleifs where tought as a choice along with that of aithisum what would be the out come? A more vaireed mix of belifes? I feel that not many people actualy consider any other religion as corect. But why not? is one faith not as good as another? there are no Stone wall facts that will prove Jeusus or moses or any other religios figure existed, it all relys of faith. So my question stands is beleif just taught?
I was taught as a chtirtian and I have many freinds of differant and veried faiths, yet I am an aithius but only because none of them have put forward a feisable case. please exuse my spelling I am more of a numbers man.
