I'd wondered if there was a site like this, and then I stumbled across it while looking for something else. Atheist Parents website offers articles on parenting and atheism, and forums where people share ideas.
The first article I looked at was a little strident for my tastes. It was written from a grandparent standpoint and referred to finding their grandchild praying as "evidence of religious molestation." That's pretty hard core. I do not know how typical that is of atheism literature because I don't read much of it. If it is typical, then that is unfortunate and wrong-headed. It's as bad as when religious folks complain about what they see as the secular world tainting their children.
In any case, theist and atheist alike should be familiar with what it means to be an atheist parent. And hopefully there are some insights on this site regarding the raising of children to be happy, contributing members of a strong, free, fair and thoughtful society.
