Because that’s ultimately what this 24/7 mask wearing is about - demanding others engage in specific behaviors to make yourself feel better.
I view this as personal responsibility and that’s how I conduct myself. I should draw boundaries for myself with what is and what is not okay and operate accordingly. I don’t expect anyone to change their life to account for my insecurities.
If I see a person wearing a mask, even one of those single-ply gaiters that seems to be much less effective than three-ply cotton masks, I still understand that they are not one of the radical science-denying people that make zero effort to avoid infecting themselves and others, and are therefore dangerous.
Personal responsibility sounds great, and is a good start. But also, we live in a society, so personal responsibility includes doing what you can to avoid spreading COVID-19 to others.
Epidemiology is not "insecurity." That's... wow, I'm not even sure how to respond to that.
CDC guidelines are about likelihood of transmission, not certainty.
It's considerate and respectful to wear a mask when around other people. If you're not going to do it, then all I ask is that you stay far away from me and mine.
