Masking here in WA has largely broken down via observable political lines. The state U still requires masks for everyone through the end of the year, regardless of the vaccination status of the participants in question (I was told by supervisors that the mask policy was still in effect, even for private lessons where both I and my student are fully vaxxed). In the organic-y groceries, eg. Trader Joes, everyone is masked; in the hardware store or office depot, nobody is. And so it goes. The posted policies on masks post-CDC revision have become a reasonably good litmus test of ideological leanings at the top level of any public facing organization. It’s not like we didn’t already know that this thing is fully politicized, but we have now arrived at a point of irrefutable confirmation.
