Your position is that America is "the greatest country possible" so the political spectrum used by the rest of the developed world is not relevant to us. We went through this exercise to illustrate that America actually doesn't lead the world in anything except defense spending and mass shootings.

The largest news organization in America, Fox News, is far-right. What you consider "far-left" is considered centrist to right-leaning in the rest of the developed world. America is not "so great" that we can't consider these classifications because America doesn't actually lead the world in anything other than death.
