Growing up in skateboarding and bmx, there was a similar anti-helmet anti-pad sort of sentiment, perhaps a similar sort of anti-authority culture.
I have two shots, no boosters, and selectively wear a mask when a situation seems to call for it, and haven't yet tested positive, but I figure it's fairly likely I will eventually, or have and just haven't tested positive. Many many people I know have got it by this point, unless they're particularly isolated, as would be true in the general population.
My impression is that many vocal people vehemently picked one extreme take or the other, likely in opposition to each other.
I wore it in the outdoors for like a week, and then on transit and in cafes etc.. I never felt particularly strongly one way or another, and still don't, but just as tiring as hearing anti-mask people go on their rants were my interactions with people who clearly wanted to be seen wearing it more than they actually believed it to be useful, along with those who were/are adamant that not wearing a mask meant you're trying to kill people.
For example, doing outdoor sports without a mask, and then putting one on to post a video on Instagram, or finding a way to bring up covid long after 2021 for the purpose of trying to bait a conflicting opinion out and subsequently beating that horse to death.
Getting stuck in any of those situations/conversations was perhaps most convincing in that I should continue not really being concerned with the opinions of others, quite the opposite of being persuaded to either wear or not wear a mask. Getting both sides of it, somewhat regularly, indicated to me that everyone has some inane axe to grind and mostly just wants someone to listen.
What I'll remember most about the pandemic was how much pointless and tiresome division it brought forth, how unhealthy the reaction was for me personally in terms of shutting everything down, and just hoping none of the vulnerable members of my family succumbed to it. The only thing I'd do differently in retrospect would be to have engaged those people less, because it never made the day any better, and good days were tough to come by.
