Just as a comment on labels, I used to be an "evangelical atheist" but this essay by Sam Harris changed my mind:

Excerpt:

...I'm not saying that racism is no longer a problem in this country, but anyone who thinks that the problem is as bad as it ever was has simply forgotten, or has never learned, how bad, in fact, it was.

So, we can now ask, how have people of good will and common sense gone about combating racism? There was a civil rights movement, of course. The KKK was gradually battered to the fringes of society. There have been important and, I think, irrevocable changes in the way we talk about race—our major newspapers no longer publish flagrantly racist articles and editorials as they did less than a century ago—but, ask yourself, how many people have had to identify themselves as "non-racists" to participate in this process? Is there a "non-racist alliance" somewhere for me to join?

Attaching a label to something carries real liabilities, especially if the thing you are naming isn't really a thing at all. And atheism, I would argue, is not a thing. It is not a philosophy, just as "non-racism" is not one. Atheism is not a worldview—and yet most people imagine it to be one and attack it as such. We who do not believe in God are collaborating in this misunderstanding by consenting to be named and by even naming ourselves.
