This is a good example of why we have the scientific method. Not so long ago the WHO, the CDC, Fauci and pretty much everyone else was talking about how fomites were the primary means of transmission and that the virus was not airborne, that even after a cough the particles very quickly fell to the ground. Now it turns out that exactly the opposite is true. How about if you don't have evidence to back up your claims you just STFU or say that you don't know. The same thing happened with masks. Since they believed (without supporting evidence) that the virus was not airborne they didn't think the public should be wearing masks. Instead they emphasized alcohol gel and frequent hand washing. What a huge fuckup. All of these people should be held accountable for being dumb fucks.
