I do not wear a mask in the car when by myself.It is simply idiotic to drive around wearing a mask.
But that brings up a question since you defend the practice. Should we assume you wear a mask in your car?
However, I see no reason to insult someone else for doing so. As before, they are not causing any harm to other people.
Those who chose to skip masks during fall 2020? They did cause harm to other people.
See the difference?
