No, the idiots are the ones who think they will find any reputable source stating that masks are largely effective against the spread of covid because they stop the transmission of most covid particles in the normal process of breathing. No, masks DO NOT STOP THE MAJORITY OF COVID PARTICLES FROM BEING EXHALED OR INHALED BY BREATHING. They may stop some, but certainly not most.If that's what you think the Mayo Clinic website is actually saying then you're an idiot, but of course we already knew that.
