It’s not sympathy. It’s recognition that Nazism is a disease any society can succumb to. It’s refusal to take the cheap option and say they’re not human. Their being human is what makes Nazism so dangerous. And we probably agree that you can’t pull punches in dealing with Nazis.

I suspect we’re using the term “human” differently. In my book it’s neutral: humanity means great potential for good and evil. Nazism is the great evil in humanity’s potential. But by “human” people sometimes mean to focus on what makes us capable of compassion and selflessness and not just brutes. There’s none of that in Nazism: it’s sheer brutality and selfishness. So in that sense Nazis do lack humanity.

I reject your claim that I’m sympathetic to Nazis. There’s no sympathy for Nazis here, just a recognition of how deeply dangerous Nazism is.
