People casually use terms like “lie” fairly freely, at least they used to do, to mean saying something said is untrue… without intentionally casting aspersions on the subject. If we can tell that someone is using this colloquial form, and doesn’t otherwise seem to be aggressively adversarial about that usage, shouldn’t we apply the best-intent-assumption to our own interpretations? Maybe it’ll even help to make the more intentionally adversarial usage more obvious.
