You can tell the ones who are using the contrarian Iogic up this way because they come in two distinct & opposite strains : the "well off" types who think rules don't apply to them no matter the circumstances (aka the Karens & the Kens) and the self described rednecks who are loud & proud about letting you know they are Trumpers/Qannon supporters (aka the Bufords & the Beulahs.)
Granted there are still a lot of people running around who aren't fully vaccinated and it's not due to any contrarian logic bullshit.
Whichever category they fall under, the anti-maskers/vaxxers are all idiots.
