There are many reasons why bitter, angry people will die alone. JPP MAGAts are no different.
I've noticed that a lot of MAGAts seek to spread their pain and bitterness onto others whereas others deal with their pain without taking it out on those around them or strangers on the Internet.
Those of us in the over-60 group, and even some younger, have physical problems, maladies and the like that cause chronic pain. Some suck it up and deal with it, others seem to relish spreading their pain to others. As a group, those who relish spreading pain tend to be Alt-Right.
This seems to be self-defeating cycle because they drive away their families by this behavior. Children grow up and have their own lives to live* and couples can grow apart but a bitter, angry person who deliberately seeks to drive a wedge between themselves and their own family is only screwing themselves.
It's for this reason that I think MAGAts are more likely to die alone while anyone left of them is more likely to die with family around them.
