Words can have multiple similar definitions with small variations. If I look up "defamation" I get:
> Defamation is a legal term that refers to any statement made by a person, whether verbal or printed, that causes harm to another person’s reputation or character. --- https://legaldictionary.net/defamation/
> Defamation is a communication that injures a third party's reputation and causes a legally redressable injury. The precise legal definition of defamation varies from country to country. It is not necessarily restricted to making assertions that are falsifiable, and can extend to concepts that are more abstract than reputation – like dignity and honour. --- https://en.wikipedia.org/wiki/Defamation
I don't like the idea of prosecuting people for this, but I don't think it's illogical.
But I genuinely didn't know that other countries do things differently. What does defamation even mean if it doesn't include the concept of untruth?
Perhaps you mean slander/libel?
Libel = defamation in writing. Slander = defamation in speech.
