Some of the most ridiculous anti-mask Tweets from trolls show a video of someone in a loose mask breathing out a lot of smoke. To make this meaningful compare it to not wearing a mask and to wearing an N-95 mask. Then look at how much of this is inhaled by others in the room wearing masks compared to no mask. Next look at how much less is inhaled by improving ventilation and air filtration in the room.
It's a great point, but, that's what's getting through to a lot of people. I've found most people in the south have never heard of any type of good mask, so obviously they can't be using them. They see a video of a floppy blue surgical mask online and they know of cloth masks and to the best of their knowledge that's what people mean when they say "mask up." Then they join in mocking people who wear masks because "obviously that doesn't work" and it's usually out of genuine ignorance, not malice.
That's how bad the messaging is in the real world.
@BE Yes, the Public Health messaging had been terrible,especially from the CDC.
