I think much of the appeal of the Left comes from a need for emotional depth thar is largely unsatisfied in our society. That, and the agonistic urge most of us are born with which is no longer sated in actual war.
Pondering where depth cones from, I would point to pain, to disease, to old age and to death.
For most Americans these things have been banished to a great extent, have they not?
Might not part of the appeal of the lockdowns be that FINALLY some part of our populace gets the sacrifices they have longed for without cognizing it?
