I think using the word insane isn’t warranted. Check out Jonathan Haidt’s book, The Rightous Mind. There are good reasons to be skeptical, it’s also evolutionary necessary. The majority can be wrong.
To be specific it was misinformation to say it was a lab leak, now it’s generally accepted. As far as vaxx goes I took it, but the politics mixing with science has deteriorated a lot of trust. Also this is new technology, it’s not zero risk.
Election wise, we have examples in history to show it happens. Why not here? What about democrats pushing out Bernie? Again I agree mostly all good. But it’s not insane to think something is not kosher.
Rather it’s insane to be so certain of these things.
