Firstly, I spat my blwdi tea out you git...
Secondly, I think I've found our issue, you are considering extreme conspiracy theories, so wild they can't possibly be true.
Here's my stance, the term 'conspiracy theory' has been weaponised, and those who make claims that don't tow the party line, or at least follow standard societal norms are labelled to be discarded.
Yes the bio weapon claims were ludicrous, there was no evidence of that, but when governments order suppression of very basic advice, from medical professionals, or claims that the virus that originated in the Wuhan area, was from Wuhan, are all just ramblings from conspiracy theory nuts, that's when it becomes dangerous. We were locked in our houses, and threatened with fines and violence if we left, far beyond the initial panic stage, and those who dared to disagree were called conspiracy nutjobs.
There was a time when Trump closed entry to people flying in from China, he was called racist, then later he was lambasted for acting too slowly lol. He was also called racist for calling this a virus from China, and anyone who made the claim was called? You guessed it.
And IMO this is where bad ideas breed and become a problem, the more social media, and governments stopped the sharing of ideas, the more frustrated the populations became, and then pop, BLM happened. I'm not saying it was a sole factor, but locking up a population and telling them they can't talk about the reason, was always going to result in a bang.
I just don't think you can stop certain people from speaking without it leading to authoritarianism intended or not.
