Oversimplification. This isn't just an atheist. This is an atheist who hasn't grown up, and found that even without some mythical god stating what is right and wrong, there are still universal truths. Sadly, too many atheists get caught up hating the religion part of religion, they lose sight of the rational philosophies those religions were intended to teach and pass on. Not that religion is the only place to find wisdom, but a lot of atheists reject anything religion says. Really, they're not atheists, they're nihilists. If a god wasn't there to define it, it has no objective definition, and so they needn't believe anything is right or wrong. I'm atheist. I believe abortion is wrong, because it requires killing an innocent. I believe marriage is right, because humans live more optimal lives in monogamous relationships. I believe gays and trannies are mentally and/or physically ill, because they don't exhibit the behaviors that define male and female sexuality throughout all sexually reproducing forms of life. I believe we should take care of our bodies because it's what's best for us, mentally and physically, a fact bourn out by countless medical and scientific studies on all forms of life. For me, as an atheist, I simply don't believe in the mythology. But the wisdom of the stories, when taken in context with the time it was written, the events taking place, the events described, and the symbolism...I can only conclude that those lessons were hard learned over centuries or eons and finally written down, and codified, and spread far and wide, to do all those things religion was intended to do. To bring heaven on Earth, and to bring peace, and prosperity, to all who accept that divine wisdom, and practice it in their lives. Religion is the most important and powerful invention atheism has ever created.
