This isn't stupidity. This is intentional. It's tribalism that leftists love so much: you cross me and you're out of the 'good' group. Where they lose their damn minds is in trying to make 'groups' out of characteristics no one controls, but base membership on actual behavior. They do this because they're playing every emotional side of every argument, and no logical side of any argument.

It's a strategy of manipulation that only the 'over-educated' would enjoy. It requires that special kind of arrogance that comes with seeing yourself as better than the rabble around you.
