As for Jon Stewart and his boneheaded remarks/"joke" about masking...
I have few friends who bother with masking at this point and they're left of center. Presumably people who *should* care but mostly don't.
And this is one reason why I don't put much effort into maintaining a social life at this point. It's fucking stressful being surrounded by people (most people) who just don't give a flying fuck about this stuff.
