Many have coronavirus and don't know it (asymptomatic).
The thing is, that the mask is not to protect you. It's to protect others FROM you.
You are in fact "exercising your freedom to choose" to endanger those around you, which you are NOT in fact free to do so.
It's the equivalent of walking around pointing a loaded gun, with the safety off, finger on the trigger, at everyone you come into close contact with.
So please, do us all a favor and holster your mouth AND nose when amidst the public and particularly when entering any enclosed space shared with your fellow citizens.
Unless you're a terrorist and/or a psychopath and don't care how many folks you inadvertently infect, thus this whole post is moot.
