Am I being unclear? You are asking what my answer is, and I've said it multiple times.
I asked what your solution was for people in my situation with family members too young to wear N95s. I guess I missed your answer to that other than some strawman thing about how it's high risk to go to school.
I also pointed out that N95s aren't perfect, but you decided you don't believe me, which: *shrug*. They're really not. And most people don't know how to wear them. Medical professionals have to be trained and fit tested to wear them correctly. (Remember those pictures going around social media of doctors and nurses with their faces all marked up and bruised? That's from N95s being properly worn all day.) Plus they're not recommended for some people with heart and lung problems, which, hello, people vulnerable to COVID! It's just not a 100% universally acceptable recommendation that lets you write off 10+ million Americans as "they can take care of it themselves, so it's no longer on me to worry about it".
I realize that you've bought into your own idea so hard that you're never going to let it go no matter how illogical it is. You don't have to keep arguing if you don't want to, you seem to just repeat the same single thing over and over.
That really sucks. Have you talked to a lawyer? At least the building staff might respond to a demand letter.
Believe it or not, I've had an extremely stressful year with a lot of health problems, and this is about the last thing I need on my plate :-) I've written to the building admin about it. The only thing they ever do is send out e-mails reminding people to wear masks. And there are signs up. But there's no actual enforcement because there's no staff in place to do that sort of thing.
I don't think that this pandemic is going to end because people wear masks. I don't know of any epidemiologist that has said that in recent memory.
It won't end because of one thing. Masking will reduce spread, vaccination will reduce spread, social distancing will reduce spread, natural immunity will reduce spread, and all the things together will (hopefully) reduce the spread until it stops being a runaway train for long enough that we get it under control somehow (maybe with a really effective treatment, a better/updated vaccine, or more widespread vaccinations with the ones we have now).
