Lot's of good studies - all with links normies and lefties would find credible.

However, my normie friends would still say, "yeah, but I feel safer wearing one to protect myself and others, plus the CDC says we should" (despite the fact that the CDC is referenced all over the place in this article)

My leftie friends would say, "I stopped reading at x, y, z" and shut down any rational thinking or conversation.

I'm running against a brick wall - people on all sides are pretty much set in their ways.

Saving and bookmarking. Thank you for posting exactly what I was looking for. I need to present to some folks at work , who are definitely going to ignore everything I say. But I've got to try.
