So-called social Darwinism was the precursor to Nazism. It was the politics of the German trenches.
It is the sort of thing people who know very little about Darwin think is what Darwin was implying. It is the very politics of brutallism which inspired Hitler.
In fact, it's the description of social Darwinism from which I get my vocabulary of brutallism when describing the GOP. They are going there. In this politics, the poor aren't unlucky, they are lazy; minorities aren't vulnerable, they are like vermin. Next thing you know, there are concentration camps. Wait. There are.
That's the road the GOP is on.
