An intelligent person would listen to the bulk of knowledge from virologists, epidemiologists, public health experts, and other scientists, etc.
But this commercial isn't made for intelligent people, because they're already doing the intelligent thing. Now they're working on the misinformed, the poorly informed, and the illogical, and for them there's no silver bullet so they just throw whatever they can against the wall and see what sticks.
Your dumbass hasn't named one scientist or doctor. FOH.
