I did no such thing. I cited it as something that contributed to my lack of a belief on this topic. I recognize that it would not suitably motivate any belief; it's just competing with an equally unsuitable intuition to make me have no particular interest in the answer to the question. If I had a belief on this topic, I would not cite my optimism about human nature as evidence.

The confusion comes from ambiguity between lack of belief as disbelief, and lack of belief as not looking for evidence and thus lacking strong opinion either way.
