Because the mask doesn't prevent you from being infected by others, it prevents you from infecting others.Betcha I catch hell for this... Betcha I don't care.....
I am tired of hearing folks tell me that if I cared about them not getting the virus I'd protect them by wearing a mask. Better yet in order to protect them I should stay home.
If YOU don't want to take a chance getting the virus how about YOU wear a mask or YOU stay home. Voluntarily restrict your own freedom/rights instead of demanding, and expecting the government to enforce, my freedom/rights be restricted.
But kindly do not act all noble while blaming me for you getting sick.
