Occam's razor here is that your interest in masks is a mental illness, and not because someone in your family is so immunocompromised or whatever that the mask is standing between that person and certain death. Is it possible that the latter is the case? Maybe. But in my view almost all cases of people stubbornly wearing masks are just psychiatric in nature.

I know my comment will just make you angry, because "you're different". But, maybe someone else will see it and consider their psychological state on this topic.

I wish upon you severe illness and the humility to deal with the repercussions to your worldview, and happiness.

I wish for your life to be long and healthy; and the lives of your loved ones too. And in that, let me give you advice to trade for your judgement of my place in life and my actions and sacrifices and loss. The advice is this:

Read. The academic. Literature.

I know a family who still wears masks in public because their daughter is very sick, very weak, and they don't want to risk her getting covid. Perfectly sensible. I also know people who wear masks in public because they're a little nuts... just can't let go, or politically or psychologically hung up.

So what can you say? You see a stranger wearing a mask, you don't know if it's for a good reason or not. Probably the odds are that it's an emotional or psychological hangup, but it may be for a really good reason. So you need to just shrug and let people do what they think best for themselves. They're the ones responsible for themselves.
