Nobody is showing atheism to children. I will have no problem if my kids decide to worship oaks, snakes, thunder, Jesus, Allah, Buddah, Thor, Odin, Seth, Anubis, Manitou, Osiris, Huitzilopotchli, Zeus, Lucifer or other numerous gods created by man's fear and darkness... Just let them have freedom of choice. And unfortunately in most countries they do not have it.
That is entirely based on yoru point of view now isn't it? Athiest think religion is being forced on them and religious people think that no religion is being forced on them. (generally speaking)
Amazing how ones perception changes depending on what side of the fence they are on.
As for the bolded part well you are talking to people who mostly live in places where they do allow that freedom so how does your comment on not forcing religion down your childs throat apply to us?
