Having seen another thread here discussing the intelligence of one side vs the other. People get very strident regarding how they are "right" and the other side is not only wrong but not very intelligent. This then escalates to name calling, then a it's a shade of a jump to demonizing others. I hear people getting physical because some won't wear masks or getting physical because the people are wearing masks.
My fear is reflected in the page below. Some may think I'm being silly or "it's not really that bad". My point being, this is how division becomes irrational.
