Fair enough, except it's not our responsibility to prove that something doesn't work. It's up to the mask-pushers to prove that it does work, and that it works well enough that I'm willing to use one voluntarily.

And studies like, "we forced a pressurized bacterial spray through a mask onto a petri dish and after 10 hours, there was less bacteria on the experimental petri dish than in the control dish!" aren't convincing.
