I think the biggest difference between the cuck and non-cuck wings of the Republican party (apart from the cucks being liberals) is that non-cucks valorize audacity and aggression, whereas cucks valorize caution and defensiveness.
In a period of relative political stability, caution and defensiveness are what get you through. There are apple carts that don’t need upsetting, so people will tend to select for those traits. The problem is we’re in the middle of the political realignment where everything is up for grabs, and new arrangements are being negotiated. In that kind of political environment, audacity and aggression are what will get you through, but it’ll take a while to move aside all the people who rose under the last period of political stability.
I’m not always happy about the battles Trump picks, but he’s a fighter. He is a harbinger of the realignment. We will need more politicians who fight.
