How about posters spreading misinformation about a pandemic, like that masks don't work?
Show me proof that masks work.
I don't care what the CDC says. The CDC says Obama's party and BLM demonstrations/riots aren't superspreader events, but Sturgis is. So show me studies that verify the efficacy of masks. Statements by Dr. Fauci aren't studies.
There used to be invention called "Google" that lets you find these kind of information on your own, if you're interested in them. You don't need other people for that. But whatever, here you go:

Of course, the spread of the virus in open spaces is always much more subdued and therefore somewhat negligable compared to the spreading rate in closed spaces. This is why I never really obeyed my own government's rules on wearing masks in the open as opposes to closed spaces - based on the scientific asssessments I had read.
I'm also pretty positive that "CDC says Obama's party" constitutes some form of logical fallacy.
