Wanting to put the cross on the kids crib and left them play with the Bible is not aggressive? But him say, so, no I don't want my child to have these is?
That is a bullshit argument. She A BABY right now who is not capable of deciding for herself. Projecting into the future of what may happen to make the OP seem like a controlling asshole is disingenuous.
I'm an atheist too. If I had a child, I would go out of my way to expose my child to all faiths: Christian, Muslim, Buddhist, Hindu, etc. because understanding where people are coming from culturally is important knowledge that all people should learn. I would not allow my religious family to force too much of their religion on my child. Aka, I would not want my child coached early on into what the "one true faith is" during their formative years. I would celebrate Christian Christmas, along with Hanuka, Ramadan, Diwali, Kwanza, and the like to expose them to the core tenets behind each faith. I would also immerse them in museums, history, science, zoos, and logic. As they grow older, if they show interest in a faith, I would do my best to help guide them toward the knowledge they need to follow that path.
There is nothing wrong with exposing kids to faith. What is wrong is when they are only exposed to one faith. How can a kid chose their own belief personal when the parents shelter from all but one?
