I have diabetes as well. I think I had Covid, or was sick twice in 2020, first in February and then again in December. I rarely wore a mask in 2020 (two five minute periods), and for awhile was shopping at a Mexican Grocery store when the mask signage went up at Krogers. I later shopped at Kroger unmasked and no one except the PSA in the grocery store said anything about it.As far as the vaccine went, I was never going to get it...being that it was experimental and new..I said I would wait at least three years until all the studies came out about it and because I knew, even with diabetes and a-fib, I was still at low risk of dying from Covid.

Mass formation has nothing to do with education only that the more educated you are, the more prone you are to it. My guess is one of the factors is the tacit agreement that the system of education and logic is infallible. A person who is educated is more susceptible to buy into "consensus thinking."
