No. You would have to find the fault amounted to at least negligence (meaning your claim was made baselessly and without any thought or consideration at all). Simply being incorrect isn’t enough, you have to be incorrect and have been wholly and completely negligent about making the statements.
Xondono would also have to show they were damaged and harmed by the statements, which would be difficult to prove.
If a newspaper falsely said that someone (let’s use a non public figure in this example, as there is a different standard for public figures, making defamation more difficult) was a child molester, that in and of itself isn’t instantly defamation, even though the person can easily show they have been harmed and damaged. You would need to show that the newspaper did zero or near zero due diligence into making the claim, meaning they were negligent. If there was evidence supporting the fact that someone was a child molester (even if the claim was untrue), that could show there wasn’t negligence involved. It very well might be libel, but it wouldn’t be assured.
This is one reason it is important to say things like “alleged” or “ in my opinion.” So if I said, “in my opinion, xondono's understanding of the law is incorrect,” I haven’t defamed xondono, even if my opinion is wrong and even if he feels harmed by my opinion.
Where this gets interesting is with the Dominion Voting Systems lawsuits against Fox News, Newsmax and various on-air personalities. In this case, Dominion (https://www.washingtonpost.com/media/2021/03/26/fox-dominion... ) is arguing that by amplifying statements that were false, what Fox News did was with “reckless disregard” for the truth. Meaning Fox was knowingly lying. Usually, Fox News would probably have an easier time defending itself, but Dominion argues that Fox ignored its outreach to correct the record. It’s also arguing that debunked claims were continuously amplified after being debunked, because those false claims led to higher ratings. As a result of the libel lawsuits by Dominion and others, other networks like Newsmax have gone as far as to withdraw their false claims on the air and publicly apologize. Dominion may still lose its lawsuits, but it’s a much more interesting defamation lawsuit that could have significantly more of an impact on other companies, including Facebook or its fact-checking partners, than whatever Stossel is trying to do.
