SA, J can prove me wrong at any time just by engaging; discussing properly, as an equal. It is purely a matter of choice. J is wrong about the pandemic and therefore may be unable to answer some of my questions without contradiction, but it is still J’s choice whether to discuss, or to maintain silence so as to avoid exposing the errors in his assertions.
Such choices are made every day within the scientific community, but certain standards of discussion are compulsory, in that refusal to discuss amounts to leaving the scientific arena. It’s somewhat like sport. You can’t win a championship merely by refusing to play because you claim all your opponents are evil, but you can’t win just by breaking the rules either; you actually need skill and ability, and you need to exercise them.
It is both a massive shame and a major problem that our politicians and “news” media set such a low bar with their appalling examples.
