Yeah, I don't get that either. Prior to contrary belief, I'm not one of these unhinged anti-maskers. If you see me out, you'll see me wearing a mask-properly.
That said, I think it's dumb. I don't think it helps one iota and I can't believe the people who stand in righteous indignation of others for not masking, knowing their mask is more than likely, unwashed, been wore way too long to be effective, or can't even be troubled to wear it properly.
Follow your own dogma Pharisee of the masks...
