I am wondering when to start teaching my son about Atheism. He just started Kindergarten in a Utah school, so I know the theist discussions (especially regarding mormonism) are coming, it is just a matter of time. What I am wondering is whether I should wait for the questions and start teaching him then based on what he is asking, or if I should be proactive and start before he comes home with questions. My only hesitation to starting now is the fact that he seems to have no concept of what the word "god" even means, let alone any idea of what religion is or what it means. Opinions? What approach do all of you take with your kids, and why? Please be specific. Thanks!
