I wear a mask every time I go to grocery stores, Costco, Pet Stores, etc. not to prevent me from becoming infected, but to show respect for others. In every outing in my community, and every home in my town (43,000 pop) and all along the 680 Corridor the vast majority follow the recommendations of the Gov. and local officials.
The rare outlier always shows up on the local news stations, inc. Fox, having a fit because they are being shamed for not doing so, and are not allowed to enter the above noted shops when unmasked.
This effort to convince the masses doesn't work here, where most of the adults hold college degrees and no home is valued under seven figures. I'm not suggesting all trump supporters are poor and uneducated, but not wearing a mask shows disrespect for others, which seems to be the on going ideology of Callous Conservatism.
