2 Is far too young to be forming opinions and fully rational thoughts about religion. I think it's perfectly rational and cumpulsory to protect your child from any influences you deem as hazardous. Shielding them from outside influences they will see as adults though, might backfire in the long run. For now completely shield them, but if your child was 10 and said the same thing how would you react? You can't help but influence (read as force) your ideologies onto young children, because they experience what you do in a large part. My children enjoy Church and believe in God and JEsus, because I bring them with me when I go. If however they have questions about it, or feel like God doesn't exist I'm also fine with that. My kids are a little older than yours though. In general I've found that not making too big a deal out of anything at the younger ages (whatever to focus) us usally the better path to take in the long run.
"There ought to be a term that would designate those who actually follow the teachings of Jesus, since the word 'Christian' has been largely divorced from those teachings, and so polluted by fundamentalists that it has come to connote their polar opposite: intolerance, vindictive hatred, and bigotry." -- Philip Stater, Huffington Post
