that kind of hairsplitting on masks is why nobody is bothering to use them

ANY object that obstructs airborne saliva/droplets during a 30 minute supermarket shopping spree for example from entering your membranes will help, to varying degrees. It is fucking obvious to PLANET EARTH MINUS AMERICA.

to varying degrees, with the palm of your hand being least effective over an hour's exposure, to a totally covered nose and mouth being the most obviously effective.

Now go right ahead and hairsplit, because all it does is discourage people from trying to protect themselves and others. How ELSE would you explain ANAL RETENTIVE AMERICA VIS A VIS 200 OTHER COUNTRIES IN THE WORLD WHO WEAR MASKS WITHOUT WHINING?

I cant even believe Amerigan people are debating this.
