For a tautology to work it always has to be true.

Sorry to butt in, but I think I might know where the confusion is coming from. Apart from its strictly logical meaning of “a statement that’s always true”, the word tautology is often used to mean repetition or circular circular reasoning (e.g. “I should join this honor society to show colleges I’m honorable, and I’m honorable because I’m in an honor society?”).

Even by the article you linked, it’s not wrong to point out a fallacy. It’d be wrong to conclude that since the argument was fallacious, the opposite must be true, but the local man didn’t say that.

He didn’t say otherwise, just pointed out the argument used was poor.
