Having philosophy background, that's a little tricky to answer.
For all practical purposes I would consider myself a "category 7" on that scale.
The difficulty lies in what is being used as a definition for "God".
In debates with theists this is usually almost impossible to pin down, which of course
leaves it open to virtually any interpretation.
If one were, for example, to define "God" as "some hugely advanced intelligence capable of playing with the quantum substructure of reality as casually as we play with marbles", well, that might set me back to a category 6.
And if one were to define "God" as "Laphroaig 10 Year Old single malt", well, then -- Hallelujah! -- I'm a category 1 believer.
