I believe that learning about religion is far better than being raised in it, if that makes any sense. I was raised in it, and it did not go well. My wife earnestly wanted to be married in a Catholic church, and our children have been baptized Catholic, but they do not attend church. I was direct with my wife, and let her know that I would only attend if the kids were involved in some way that week (alter, choir, whatever), but not on the day to day.
I've discussed with my son that I do not know if there's a God. I've shared that some believe, and some do not, and all of that is fine, as faith is personal. So long as that faith doesn't hurt anyone or anything (i.e. "I believe in God and a woman's right to choose" or something like that), it's fine. I shared that people kill and die in the name of religion and, while I do not attempt to speak on behalf of a God that probably doesn't exist, I do not believe that is what it would want.
For me, religion was a source of fear, and never (in memory) a joyous or love creating thing. I don't want my children crying in the bathroom because they're afraid that the devil will come and get them. I don't want them thinking they're damned for eternity for normal human feelings and physiological changes their body goes through, either.
Religion is a source of lots of things. Art, architecture, culture, etc, are a wonder to behold. Inspiration to create and truly express oneself is a beautiful thing. But I don't believe that religion is a requirement for that. If anything, personally, it has served as a barrier. I wouldn't change a thing (for the most part) about my life experiences, and how "God" has impacted them. I can say that my life would be different were it not for that influence. But I do not believe that others should have that hanging on them. Guilt, fear, and bruises were the return on the investment I had in religion by chance of birth. To each their own, but I will continue to share with my children that I don't know, that no one really knows, no one has ever really known. They believe. I don't believe. Whatever my children believe, they have my support so long as what they share with their children (if they have them) is shared, and not forced on them.
