So when popular opinion agrees with the truth it is valid, but when it doesn't it is fallacious? Since it has no bearing on the veracity of a thing, it appears to be quite irrelevant either way to me, but then I'm just a mundane...Ad Populum is a fallacy if and only if the popularity of X is irrelevant to its truth-value. This, of course, could conceivably be a point of contention here.
