Your argument is tired and juvenile. It’s the classic “if only we masked up harder!”
Look at places like Japan. COVID spread there like wildfire. I guess they didn’t mask hard enough? Haha. No. Masks didn’t make a fucking difference in the most compliant place in the world.
Also, it’s not conservative versus liberal. Somehow masks got tied up in political theater, and now people like you use the mask to express your political affiliation. You love the mask because it expresses left wing to you, and you think that right wing is evil, so you become obsessed with masks. Maybe if we all recognized that one or the other side is not evil, and has no intrinsic connection to masks, we’d be better off.
