@SNP1 that's not true, I'm not agnostic, I"m a Gnostic Atheist, and yes I know what that means, it means I KNOW there are no gods. This is a personal issue-so you cant lay your person on everyone and assume nobody knows either way. The fact is, many people claim to know-most of them are Gnostic Theists, and obviously either gnostic atheists or gnostic theists are wrong-both cannot be right objectively. Back to the lesser known example, it's the same really-a religious experience that leads to gnostiicism, but in the case of the atheist-obviously it would be from an atheist faith, like Buddhism.
Nor would you give LDS (Mormons) a separate category-because they too are covered under "christian' it's a public forum, not somebody's personal clubhouse, where they get to say which christians are fit to come in and which to be left out in the cold. But it does reveal that exclusionary delusion many chrisitians have.
