Oh, wait wait wait, no, those people are actually right, it's the ones saying it _is_ happening who are wrong-thinking. Got it. Let me check my notes again; it's the global warming that is definitely happening and cannot be denied, and the great replacement that is definitely not happening and must be denied (or alternatively you can acknowledge it but say it's actually a great thing).
Do you see where I'm getting at? We must debate all those things in a healthy democracy. We can debate whether Russia or the US is right regarding the Ukraine. We can debate immigration. We can debate vaccines. We can debate whether or not it's true that Saddam actually has WMDs and whether it's wise to invade Iraq. We can debate whether or not smoking causes cancer. We can debate whether or not there is actually a risk with asbestos. We should debate all this stuff.
In case my point is not clear in a sarcastic form let me be more explicit: history has shown that we have been wrong about so many things in so many fields (medical, diplomacy, etc.) over the years. And conventional wisdom about certain things can completely flip over time. Thus we should never exclude debate and skepticism.
Militant extremists, climate change deniers, COVID misinformation, antivaxxers, etc. And he's generally credulous. He had Jordan Peterson in doing climate change denial just the other day.
This misinformation has material negative impact on all our lives. He's like Paltrow's Goop but for men.
And while we have freedom of speech, we also acknowledge as a society that some lies are too dangerous to allow -- that's why fraud, perjury, slander, filing a false report, false advertising, etc. are all illegal. It's just that reality itself can't sue for defamation.
