Unless Allyn Gibson did not in fact post things to Facebook criticizing immigrants and Black folks, or the Gibson family does not in fact own a huge amount of real estate in town, there's no possibility of any of that comment being libelous. Anybody can call anybody racist any time: that's a statement of opinion, and opinions cannot be defamatory.

So Elon Musk calling that guy a pedophile was an opinion and therefore shouldn't have been considered defamatory?

Realistically any opinion based comment could be taken offence to and then whether it is defamatory or not depends on the evidence that individual has for having said opinion.
