I mask bc I have lyme disease that predates the covid pandemic, and even before I finally got a diagnosis in 2023, I was obviously sick enough that I didn't need to add anything else to my immune system's tab
Even if I make a full recovery someday, I would *never* risk having such an illness again
Masking also isn't a categorical kind of rationality either. People have different reasons.
I mask because, as someone immuno-compromised, the risks are significantly higher. There is no simple way to handwave masking as irrational and fear-based unless you unpack how each person makes decisions.
