I don't consider it implausible that c*vid escaped from a lab but I think it's notable that, solely because it implicates an unfriendly foreign government instead of our own, it's a reasonable question and not a lunatic conspiracy theory https://twitter.com/nickconfessore/status/1246153609210970116 …
The really advanced conspiracy theory involves labs in both China and the US. Not sure if it's a syncretized version of the narrative the CCP floated a while back or if they pulled that theory out of a bigger one involving Wuhan and Chapel Hill.
