maybe to a different question....i believe the question was whether or not the left-right paradigm was obsolete or not....i contend that it is just as relevant today as it was in the past...if you base it upon a line of force...
as you point out in another post Americans did not just come out of the blue but had roots from other parts of the world.....settlers came from various places and from under other forms of government that experienced various degrees of force.........left-right are terms that i'm not sure where they came from but they are useful in describing the basic continuum from totalitarianism to freedom....America was exceptional because it was formed on the right end of that political spectrum....
the way i see it we here in America have moved to the left and both parties are sitting today somewhere in the middle of the graph....except for some elements which uphold the principles of the right that we started with....
The fallacy is, your "lines of force" in that chart bear no relationship with any reality whatsoever. It's a joke. It really is, with no exaggeration, the worst political spectrum chart I've ever seen in my life. Literally.
on the contrary this is reality because force has everything to do with it.....government = force....you can put any political structure somewhere along that line...
progressives hate this chart because it clearly shows the left for who they actually are in the political spectrum....
one reason the right has such a hard time of it in the battle with the left....it's tough to fight against those who promise (false) 'equality' along with handouts in exchange for fealty to their growing power structure... while all the right can really offer is an equal playing field and the freedom to be responsible for yourself...
I don't know about "progressives" but I hate it because it's bullshit based on pig-ignorance that seems to have no purpose but to demonize and polarize on behalf of the principle of Eliminationism, i.e. one-party rule, which is by definition bullshit.
Both left and right are capable of "force" for their own purposes. Not to see that obvious fact is to bury one's head in the proverbial sand.
