Is there an established theory that the further left one goes, or the further right one goes, they end up in the same place, as though the political spectrum is in fact a circle with extreme-right and extreme-left meeting at the opposite side of moderate?
In other words, one can go in either direction and ultimately become an uncompromising totalitarian (if you are in charge) or a terrorist (if you are not in charge) to a point where it does not matter what idealology lead you there.
I have never seen this in print so I'm wondering if any of you have.
