A very interesting film was shown on PBS Nova series titled "Natures Fear Factor."
I think they had folks back then that also thought masks did not work or refused to wear them. There were not as many as today and it certainly was not as political.
Around here at the grocery store you know who is a trumpster - no mask - even tho there is a state mandate to wear a mask in public when inside or you can't be over 6 feet away from others.
