Yup. I think "force of habit" undersells it, except to the extent you are a collection of habits. Plus trying to encourage truth-seeking as opposed to truth-labeling as a goal. That is, the phrase you like is "We often say, here, that that which can be destroyed by the truth should be"
But you're not destroying her belief by the truth, you're destroying a belief and replacing it with the truth (ish). At least, as you describe yourself. Other stuff (that is, I think this is one of dozens of arguments for why this way of thinking is foolish: more interesting to me is the degree to which the sensible upvoted comments on this page - be nicer and more respectful - lack explication or mechanism).
Not really. I listed some reasons elsewhere, but they're pretty arbitrary (which was more or less the point). Also, not sockpuppets in the conventional sense since clearly not disguised and I will never count backwards.
