You're probably right about us all being nerds here. Although, I tend to think of myself more as a geek, but the point remains valid. I'm not specifically trying to persuade nontheists of my views. I actually spend most of the time offline trying to persuade the "spiritual but not religious" crowd. They're usually my target market and I slowly dissuade them from supernaturalism of the various types. Although, I guess they too are a little turned off by the word religion. They generally agree that it is the level of organization, the form if you will, and not the content that defines religion.
As I say this, I realize that you might be right after all. I guess I am trying to persuade people generally that have been turned off by religion, because those that are happy with religion or seldom in the market for a new one, even a nonsupernaturalist one.
