Wow! Justin Martyr you just described exactly what I do everywhere I go! Thank God that most places (although the sign "demanding" mask-wearing is present) I don't have to wear a mask and no one says anything. I hate confrontation, but yes, I will politely argue and even explain some fallacies, many times when I walk into a smaller store and people see me without a mask, sometimes they'll lower their mask or remove it, of course you do have those people out there who'll look at you funny, most of the time I just walk on and pay no mind.
I always want to refuse the mask as much as possible. There is one store where the owner and I are quasi-political opposites, and he has flicked me off pointing to his mask, giving me an evil stare and I just asked him if he was flicking me off and his eyes just got bigger and bigger pointing to his mask.
Now because I'm self-employed and consider myself (occasionally) to need his business, I know when I go there I'll have 2 wear a mask
