where did the 6 ft distance rule come from. Because the WHO claims 3ft based on zero actual evidence this would work for an aerosolized virus.
Old studies suggest that larger respiratory droplets are unlikely to travel more than 6 feet, and therefore close contact with an infected person is the primary mode of exposure. This research was hardly conclusive, but by most accounts it formed the basis for the initial Covid recommendations. You may or may not be aware, that at first covid's aerosol spreading was not known.
Where did the barrier rules come from, because scientists for decades have known that ventilation works best without barriers.
Probably the same as in the previous, droplets. Still, afaiu, no one's ruled out droplets as a spreading mechanism, just that it also travels via aerosols.
Where is the evidence surgical masks work at all for hours or days without replacement, let alone cloth face coverings, because all available evidence shows that they are not effective in a public setting.

Where is the evidence that kids are the main vector of infection and need to be isolated and wear dirty, wet masks all day that in some cases have given them fungal pneumonia.
