I’m continually amazed at people’s hunger for toughness signaling. I’m going to hazard that the modern American form of it started with professional wrestlers, who are basically anger clowns, like Ann Coulter. They have these pretend rivalries, and the villains are so very villainous. Also see comic books, where villains are “bad guys” and heroes are “good guys.” And Westerns.
Toughness signaling has to do with strict gender dimorphism. Those who feel that the blurring of gender boundaries threatens their very identity, engage in toughness signaling to confirm their manhood.
Of course, toughness in a vacuum is idiotic. You need a threat. That’s why Trump needed to claim that there was “carnage,” and why some folk claim there is “white genocide” or “lynching.” It has to be a very dramatic threat, after all, to justify the level of toughness signaling they feel they need to perform.
Here is a UN document on atrocity crimes. Heavy reading.
I am reminded of a domestic situation (let’s leave it at that level of detail) in which one party is irritated at what the other party does, and reacts angrily. It just feels right to be angry. And that seductive feeling ramps up to even more operatic, greater expression of anger. Then the reasoning brain kicks in, and says, “you need a bigger threat to justify all that yelling.” So the angry person decides that what the other person did was not merely irritating but truly mean and horrible. Then the anger is totally justified! A post-hoc rationalization. They retroactively redefine (or “retcon”, to use comic book jargon) what the other person did, so that they’d be doormats if they didn’t express that much anger, and more, even! Because not only was the other person terrible and mean, but that is evidence of their total contempt for, not just you, but whatever class of people you belong to!
And the spiral continues until the anger burns itself out all on its own.
