The thinking to me in this is just wrong. The stuff kids learn at a very young age stick really well. While I would be happy with my hypothetical children making up their own mind, taking them to church at a young age is pretty much akin to brainwashing and will leave them quite predisposed to Christianity. I know that when I finally managed to drop religion, it was a difficult thing for me, finally realizing that everything you believed your whole life is wrong, and I wouldn't want children to have to go through that.
These days I find churches to be far more focused on fear, sin and hate than they were when I was growing up. I know they change with the times and I can think of a number of popular phases churches have gone though during my life, but I know that right now and with the current trend I sure as hell don't want children to be exposed to a "fear of god he hates you for sinning" type of message.
that Christianity at least makes more sense than some other things like Wicca.
This one makes me giggle. Because a god who comes to earth in human form to temporarily sacrifice himself, to himself, to abolish the original sin idea he came up with himself, makes SOOOOO much more sense than "the gods want people to be kind and happy, so why not celebrate by dancing naked around a fire once a month?" Which one is more internally logically consistent, again?
Re: taking kids to church:
If my kids want to stay over at a friends' house and/or go to church/synagogue/mosque/temple with them, I'm cool with that. If they have questions about my Pagan practices, or anyone else's religion, I'll answer the questions as best I can, or direct them to someone who can.
The only thing I'm NOT cool with is my kids trying to convert me if they turn out Christian. I'm cool with Christian kids, not dickish ones.
