Just one comment here. To accuse a person of lying, telling a "bald-faced lie", is not valid or fair if the person was merely mistaken in an assumption they made. A lie has to be a deliberately told, pre-planned falsehood to be a lie. A statement made in error because it is based on an incorrect assumption is not a lie, it's simply an error.

To call someone a "liar" when they have simply expressed an opinion about something is an inflammatory and unscrupulous form of attack. It's intended to hurt the person, not to illuminate or further the discussion in any useful way.

Other than that, wouldn't it be nice if we could all get free of our internet "arguing and being right by making others wrong" addictions? I know I'd like to. ;-D If I do, you probably won't even hear from me anymore on most of these debates, and you can enjoy imagining that you got in the "last word" until you forget about the whole thing eventually and find something real to do instead.
