I've seen this phenomenon many times with so-called "fact checkers", where they "disprove" an argument by either being ridiculously pedantic, or by offering some kind of non-sequitur.

One of my favorites was their response to Trump saying that "dangerous criminals" come over the Southern border. "That's a false statement", the "fact-checkers" pronounced, "because, did you know that crime is lower on average in border cities than some other cities in America?" Which, of course, has nothing to do with what Trump actually said-- and who is to say crime wouldn't be even lower in those cities, if border security were stronger?
