That's the problem with arguing with these people (see also homeopaths, flat earthers, anti-vaxers, creationists etc. bloody etc.). They're not really interested in data, they believe something and are going to keep believing it regardless. They'll cherry pick data for anything that supports them, ignore anything and everything as they see fit, and when presented with incontrovertible evidence, they'll claim it's rigged or a conspiracy or some other nonsense.
