As a rational person, you shouldn’t ever be in category 1 or 7. Indeed, it’s not even 100% that the sun will rise tomorrow. Still, almost definitely it will, to the extent that I’m not agnostic about the question. The problem is that a lot of religious people claim to be in category 1. Pretty much everyone who is an atheist is in fact in category 6. However, because of the existence of all those category 1 religious people, people try to look for symmetry and say that atheism is only category 7. Most ‘agnostics’ I’ve met are also in category 6 with the atheists, but are at pains to differentiate themselves from the strawman category 7 atheists.
