I see it this way: Once they say yo don’t have to wear a mask if you are vaccinated, it means that all of us anti-mask people can stop wearing masks. It would literally mean the end of masks in short order.
That’s the bottom line.
Only two counties in my state (Kansas) now require masks although schools are still masking in some areas and certain stores still require them. A private business can require masks till doomsday. They can also require pink speedos and high heels. I can then choose not to go there.
So all the counties around us are open but ours is till mandating masks. Sigh.
