Religious people view us this way because they've grown up being told that their gods are the source of all goodness and that not following their rules is flat out evil. I think we can change this perception by simply proving it wrong.
Be an atheist in public and a good person too. This forces people who think such things as, "Atheists are free to do any evil, selfish thing they want to!" to think such eye-opening things as, "Why aren't these atheists doing any evil, selfish thing they want to?"
