Do you feel the same way about seatbelts? If people choose to be safer by wearing masks, judging them is pretty extreme. This kind of attitude is what made the early days of the pandemic a mess.
This behavior can be suspended temporarily on a short-term basis when a population perceives an urgent state of pandemic or (as in Japan) when an individual says he has a cold, but it may not be sustainable at a society-wide scale beyond that. Seatbelts faced cultural resistance before adoption, sure, but much less than masks would once the acute COVID risk has passed.
What wearing the mask does show me is that a person is extremely susceptible to propaganda and likely has conformist tendencies. This isn't necessarily true in all cases but I think it will be for the majority of them. This sort of person is dangerous to bring in to your social circle because they can easily be manipulated into being an instrument of the state. I don't want to have to police my own thoughts and opinions in front of my friends and in an increasing totalitarian "cancel culture" environment this risk becomes increasingly more substantial and existential.
And you should tell frontline medical personnel that masks don't protect them, they'll be glad your non-conformist ultra intelligent mind managed to figure it out.
