Just look at all the B.S they repeated over and over about covid..hell some people are still running around with mask on even outside....Dam the only mask that might provide some measurable protection is a N95 that is properly fitted and these people are not wearing N95...let alone some of d.a ones that wear it over a beard... It is good example of how people will believe pretty much anything if you keep repeating it to them,, My observation here in Ontario..
