Maybe just start by not protecting war criminals.

This has of course nothing to do with the original question, where they fall on the spectrum of political opinions.

The democrats are roughly center-right when you look at it in comparison to major countries across the world. See e.g. https://qz.com/1748903/how-2020-us-democratic-candidates-com...

Right, but what kind of conclusion can be made here? Is US too right? Or Europe is too left? Or both are off and the optimal society requires much lefter/righter policies?

I'm not sure you can draw any conclusion here. (Except, seemingly, "I don't like this, don't have any rational argument, and so should downvote" ;)

The only one that you can make, based on the data, is that US politics trend much further right than many other places, and that talking about "Democrats" and "the left" in the same breath doesn't make any sense in a global context. They just aren't.

And I think that is very relevant when you want to talk about US politics. It defines the available spectrum.

Where outside of North Korea, Stalin or Mao had abolished private property or has a full employment guarantee?
