When you reduce selection pressure as the West has massively done since the Industrial Revolution, you get a lot more depravity (you get r instead of K), because the relative penalties to error and vice go way, way down. And vice versa: when you increase selection pressure, the relative rewards to virtue go way, way up, so you get lots more virtue.
We have no immediate prospect of an uptick in natural selection pressure, although the handwriting is on the wall. It’s out there (it always is).
But Trump is imposing artificial selection pressure (in part because he and his ilk can comprehend the writing in flame on the wall (to the depraved at their banquet, it is gobbledygook, nonsense, mere noise: mene, mene, tekel upharsin)). His basic message is simple: Playtime is over, no more pretend, everybody out of the pool, time to get dressed and back to work.
The liberals are going crazy because this strictly artificial – i.e., merely social, rather than biological – increase in selection pressure pushes the same neural and cognitive levers as would be triggered by a sharp uptick in natural selection pressure. It feels to them like a sort of death. They are terrified of death. Trump makes them aware of their death. Like death, he just doesn’t care about their whining (as much as they are used to). So they panic, and then they turn to defensive rage. It’s a tantrum.
