The US's standard allows for the eventuality of the Crank in the Public Square: it's incumbent upon the general public to understand that the Crank has no particularly good reason to believe the things they believe (and say), and thus aren't worth listening to. Overall, this results in (arguably) more desirable outcomes: we don't subject Cranks and the legal system to unnecessary interactions with each other, because what the Crank says simply does not matter. (The equation changes when the Crank does begin to convince other Cranks to hurt or harass their subject. But that's a matter for incitement or other standards, not defamation.)
