It seems peculiar to me that on a political website, few seem to know what political terms mean and from where they are derived.
"Left" vs. "Right" goes back to the French Revolution, when those who sat on the right of the house wanted to maintain the Monarchy, and those who sat to the left wanted to revise the political system. Those who would "conserve" and those who would change. Simple as that. BUT: once the house had been divided in seating, what ideologies and policies each side of the house favoured changed constantly.
Now, fast forward another couple centuries, and shift the discussion to other parliaments, and you can really attribute anything to either "leaning", and pretty much choose your own definition. From an earlier part of this thread, for instance, Nazis (the National Socialist Workers' Party) could be labelled either "left" or "right" depending upon which part of Nazi policy one chooses to compare with our rather fluid definition of left and right today. Being both workers and socialist, it had strong elements of ;what we today usually call the left. Being based on the idea of the Herrenvolk, that is nothing but purely racist, but here the new left uses that to try to hang that on the "right". Nazis were totalitarianists, which is as far from what I believe we mean today by "right" OR "left", as conservatives on the right tend to believe in and wish to maintain democratic institutions. Communism - which I think we can all agree is "the LEFT" is usually a totalitarian state of government, even though most have some kind of shadow of representative body shoved up front.
Over the years, the terms right and left have been offered up under this very flexible system of inclusion based on the political expedience of creating an "us vs. them" over-simplification of any issue. Reality is that the truth lies somewhere in the middle with an array of detail within policy that makes actual programmes acceptable to modern standards.
