This is why I won't say I'm a free speech absolutist, because I'm starting to believe things would be better if habitual liars like that receive regular floggings until they learn to be cooperative members of society instead of slimy rats taking advantage of the benefits of a responsible, high-trust society. No need to provide evidence of tangible harm like current defamation laws, just a balance of probability judgement by a jury that they willfully lied.

You can say all the most vile, insulting things you want as long as it's subjective or true. But as soon as you're caught being objectively dishonest like that, it's 5 lashes plus one extra for each citizen who petitions to deliver one themselves.

It could clear up political corruption in a month.
