From the article: "By almost any definition, this was gain of function research." So your boy the Great Fauchino is a Class A liar and perjuror. Furthermore, from the article:
"Garry wrote of the 'stunning' composition of the furin cleavage site: 'I really can’t think of a plausible natural scenario where you get from the bat virus or one very similar to it to [SARS-CoV-2] where you insert exactly 4 amino acids 12 nucleotide[s] that all have to be added at the exact same time to gain this function…. I just can’t figure out how this gets accomplished in nature.'"
Finally, look at where the origin of the virus happened: gain of function research specifically regarding SARS-type viruses that could infect humans was taking place in a lab in the exact same city as the virus' origin.
Come on. This is so obvious.
