The main purpose of science is to question and attack. To subject ideas to the greatest scrutiny. Those who decide to shut down and stifle debate – whatever they may believe themselves to be doing – are, in fact, traitors to the cause of science. Stranglers of the enlightenment, assassins of progress.
They are not alone, and things have gotten far worse in the past year or so. Science has taken a terrible battering during Covid-19, though I have always known that dissent against a widely held scientific hypothesis is difficult.
