I never reacted any different at all to those who were not wearing them. I understood early on wearing those masks were not for my protection and I really did not want to infect anyone.
The N95 masks were a way to protect myself and others at the same time so I kept up with when they'd become available and got them as soon as I could, and made a point to use them, and we gave quite a few to others. My wife brought them to where she works and handed them out. They'd been wearing cloth masks there up until then.
You're spot on about the division. Like I said, I took a lot of guff early on for wearing a mask here. Honestly, I think no small reason that stopped happening here is because so many got infected here and after dealing with it themselves they settled down on shitting on those wearing masks or getting vaxxed.
I see a few people wearing a mask when I go to the big box stores in town now and no one pays any attention to it.
