To digress:
In practice do you think Radical Left ot Right is most promising? I am a self admitted conservative, so this probably will be (Spectacularly) biased, but nonetheless, in practice:
Extreme Right:
Nazi Germany
Facist Italy
Fascist Spain
All monarchys/autocracy from Rome through Russia pre WWI
Extreme Left:
USSR
Cuba
Vietnam
China
It seems to me that, although many human rights abuses occured in extreme right controlled countries, the Rights generally had better stability, economic prosperity and even (Thugh Nazism was shocking) better human rights than their left wing counterparts. (China and USSR both had mass killings that almost paled the Nazis genocide)
Don't get me wrong, I'm not advocating either system or excusing the abuses under these systems, but do you find that Extrme Right generally came out better over extreme left?
My highest level of historical qualification is a bit of HSC Modern so I'm by no means trying to insist that this is right!
