The United States is a constitutional republic, not a democracy.
I have never claimed to be an infectious disease expert.
My “self serving opinion” is that you shouldn’t be thrown out of a store or otherwise punished for making an individual adult decision not to wear a mask. My “self serving opinion” is that if I see a person out in public without a mask and I’m concerned about that, I don’t confront them (because he or she is a person who has autonomy, as am I), I just stay away if I feel unsafe for any reason.
I will not let fear allow me to see other humans as threatening me for merely existing and them needing to be punished for it.
Beyond that, I really have no idea what argument you’re trying to make.
