LOL and LOL.
I let my kids decide their own religion, but I take them to church haha lol.
The environment is a powerful thing! When you inundate your child with a particular religion, there is a good probability that they will follow that religion. Neuroscience has shown the way environmental experiences shapes the brain, especially during the younger years. Cognitive schemas, which is a framework for how we see the world, ourselves, and others, is often determined by early experiences and their effects on brain development (i.e., Attachment Theory). As such, indoctrinating a kid with enough of ONE type of religion, you really give them a slim chance in making up their own mind.
I am not speaking as an atheist, but as a "scientist." There is overwhelming evidence that environmental experiences in children will have a drastic impact on their brain development, which will then determine their ideals, values, beliefs (religion), etc.
