I think you miss my point. I don't think there *is* a "left" in the sense that you're using the word, except in the minds of those who need there to be one to use as a rhetorical strawman. It's just cheap talk-show jargon. Leftist political thought runs a very broad gamut and many left factions take very different approaches to the same issues. My own views are far removed from those of any Clintonite, either of the Bill stripe or the Hillary stripe -- I consider Clintonism to be reactionary -- and yet to the Fox News crowd we're all "the left." As if.
I don't think there's a unified, monolithic "right" either, in that sense -- the current Trumpie populist right has no more in common with the neocon right than I have in common with a deep-fried cantaloupe. There's the populist right, the neocon right, the paleocon right, the Randite right, the religious right, the corporate/"New Democrat" right, the identiarian right, the fascist right, and on and on, and they have very little in common other than a fanned-up loathing of this supposed sinister monolithic "Left." And that's why most of the American political discourse operates on the intellectual level of a 4chan meme."OMG look what those libtards done now!"
