Well I'm guessing that because of your political ideals you're committed to the wrong position that masks are ineffective so studies like this won't convince you, https://www.bmj.com/content/375/bmj-2021-068302
I always love when someone posts like one single "study" that almost always doesn't even qualify as amateur hour (eg data mining) and thinks it's some sort of mic drop, as if there aren't 25 disconfirming studies or data points for every one thing saying masks have even a faint amount of efficacy.
