Those who wear them are proud anarchists, who spout inanities about how righteous they are. To find out their symbol is mass produced in what looks like a third world country sweatshop is indeed ironic.
Kind of like a vegetarian sneering at you and your hamburger while cramming down his own veggie burger, only for you to then both discover that you actually switched burgers.
Well, maybe, but I just don’t really see why anarchists should have a bigger problem with mass-produced stuff than other people. A mask is a mask is a mask as far as that goes, and it would hardly seem more fitting should they be using expensive custom hand made masks. But, that may just be my take on it.
