Well, we could use the word "evidence" in different ways (you requiring some magnitude-of-prior-shift).

There's a handy table, two of them in fact, of terminology for strength of evidence here. Up to 5 decibans is "barely worth mentioning". How many microbans does "Zeus ate my homework" amount to?

Think of what you're advocating here: whatever would we do if we disallowed strictly-speaking-correct-nitpicks on LW?

You may be joking, but I do think LW (and everywhere else) would be improved if people didn't do that. I find nitpicking as unappealing as nose-picking.
