If you are in a little bubble you are hardly likely to perceive it as such and therefore couldn't possibly think it unhealthy. I was taught in faith schools when growing up. It didn't stop me from thinking for myself in my teens and deciding I wasn't going to mass anymore, much to the horror of my mother. My son was never christened but I bet there are plenty of non believers here who have had their little Jonny baptised, as you do. Hands up anyone?
