My agnosticism is around knowledge of whether a being I'd call 'God' exists. I don't know. To all intents and purposes, I don't care. It's irrelevant to my life. If one did exist, up til now my life is irrelevant to it. For me, that's an intellectual honesty check on my beliefs, well, my lack of them. Until some pretty major questions about the origin and nature of the universe are answered then I see little point in being overly dug into a position. Should those questions be answered, then I'll reassess. This is as of equal priority in my thinking, actually less, to 'what is at the bottom of a black hole?'.
I could also happily recite lists of gods I don't believe in. It's probably as long as the number of gods imagined up by humans. Agnosticism to me certainly isn't a 'sitting on the fence' position because of a lack of thought. It's a word which pretty perfectly describes where I'm at with things. If I were convinced either way, then I'd use a different word.
