How is it ironic? Anarchists were a big part of the First International and left-anarchists can usually be considered to be socialists. They are not polar opposites, rather communism and (left-)anarchism are the statist and republican/federalist (loosely authoritarian and libertarian) expressions of the same underlying ideology of human equality.
Ah interesting history there, thanks. Maybe I'm using the term incorrectly
The continuum I was picturing is: big central planning government <--> little-to-no government (anarchy)
In any case, I guess I'm just restating a version of the old horseshoe theory
> expressions of the same underlying ideology of human equality
I have no clue how any equality minded person could vote republicans or trump.
I get that you want to point out the overlap of the ideologies, but I don't see how they are remotely attributable to the current political landscape. (Strictly in the equality matter)
