And the moral of the history is: in 2020 the COVID lab-leak hypothesis was considered a nasty idea, one that only uneducated, bitter conspiracy theorists could support. People have been banned from the effective monopolists of public discourse over this idea.
Then sometime around 2021 the same idea became acceptable.
Not surprisingly, this change in the public perception of this idea over social media followed the viewpoint of the major political party the owners of social media cheer for.
This is bad, bad, bad for political discourse and rational thinking!!
As far as I am concerned: long love the free market of ideas!
