One of the ways fascism crept in over the years is people insisted on having "debates" with people who refused to be proven wrong (e.g., vaccines, trans rights and healthcare, climate) even though they obviously were from a scientific, factual, or moral standpoint. All in the name of "free speech" and an open marketplace of ideas. What we need to learn is to tell these people to shut the fuck up.
@gwynnion some things have two debatable sides. Some have many. But you nailed that we lost sight of the fact that some things are just provably wrong. If it’s settled fact, I have no problem telling someone they are just wrong. If they want to continue “arguing” they are then both wrong and stupid.
