Would you please point to an example or two where it is so one-sided that it’s far from the truth?
So accusing them of slander is not particularly believable. I'd need to see a specific claim, evidence that the claim was false, and evidence that the falsehood rose to the legal standard of slander. A bare claim, with no evidence, just looks like overheated rhetoric by someone who doesn't like The Economist's position, but who can't actually do the work of refuting it.
It would be slander if I said the words "HN user drw85 has never said a sentence that didn't contain racist abuse", even if my saying it has no impact on you or anyone at all.
(Just as it would be libellous - the equivalent of slanderous but for written rather than spoken lies about people - if I wrote a comment here on HN accusing you of being a mass murderer, even if you don't notice the comment and no law enforcement ever consider it of interest nor any other effects.)
'a false, spoken statement about someone which damages that person's reputation, or the making of such a statement'
I guess the distinction is important, because i could make a false statement that is not damaging, like 'swores has a red nose.', which might be a joke and thus is a false statement but not damaging nor slander.
The legal system has recognized truth as a wholly adequate defense to claims of defamation (which includes slander) dating back to 1734 [3] - before the Constitution even written (1787).
