There has not been a single scientific study proving masks prevent the spread of the virus in the community. It is all a fraud. Plenty of medical doctors have publicly trashed the “mask police.” There is no science behind this tyranny. Sheep to the slaughter.
Do you believe that Costco can require persons that enter their stores wear a mask?
Do their employees have the right to ask a customer to put on their mask?
Does Costco have the right to toss a person out of their store?
Other than like a century or surgeons all wearing them. Really this “no proof” line is STUPID and anybody using it should be embarrassed. You’re the fraud.
Common sense would lead me to believe that if someone’s cough or sneeze is held back by his/her mask, that is doing something to prevent the spread.
Whether or not the mask is protecting the wearer in an environment where others aren’t wearing them is a different story; most masks clearly indicate they WON’T protect you.
