All religion is opinion.

[bitterross]

27. I agree with you. Even we Atheists adopt opinions.

I know that once I began questioning the religion into which I was born and initially indoctrinated I looked for the opinions of others. I went to the library (before the internet and google) and read. Probably not odd at all, my reading was in the Science Fiction section more than in philosophy. Authors in Science Fiction have long been presenting an alternative view of the universe unencumbered by a God or viciously ruled by malevolent ones in order to make people think.

Harlan Ellison's short-story "The Deathbird" in his compilation A Pantheon of Modern Gods really changed the way I thought as a teenager. The story positions the Serpent in the Garden of Eden as the protagonist.

These days I read Sam Harris and Richard Dawkins and others. So, yes, your thesis is correct for religion and atheists. The difference is the factual basis rather than faith for the opinion.
