Haven't Nazi Party done any good work really?

Not so sure about the "staunch" part but certainly in its early form National Socialism was grounded in expedient socialism but that rapidly mutated into something that no socialist would recognise as socialism. As is pretty evident, Hitler's socialism was a long way removed from communism since one is primarily an economic system while the other is predominantly a political ideology so are non-comparative. Politically Hitler was an authoritarian centrist (slightly right of centre but not certainly not an extreme right-winger that modern fascists tend to be) but notions of left and right are all relative - Hitler would appear left-wing to someone more right-wing than him and as a right-wing to someone more leftist (and frankly apart from Pinochet everyone on the planet would probably regard themselves as being more libertarian than Hitler).

Good. Bye.

Precisely 

Well, outside W Europe and USA, all kinds of systems have been experimented with and often with disastrous results.  So while the way he presents it is hyperbolic, to some extent I can relate to his fear.  Once the state becomes greedy to hold onto power, there's no saying where it will stop.  Maybe the ideological meaning of communism is something different but when the experience of govts run by self proclaimed communists is consistently bad, it is difficult to accept this dichotomy.  Calcutta, now Kolkata, was once the pre-eminent metropolis of India and the communists ruined it.  Imagine living in a democratic country and not being able to cast your vote because the goons employed by the communists won't let you within a hundred feet of the voting booth.  And the central government won't do anything about it because...good ol' electoral calculations. Dictatorship of the proletariat indeed!  Like many others, my family fled the despair of Calcutta for the urban sprawl of decadent capitalism that is Bombay.  The point is once you accept in principle the idea that property can be taken away from an individual and vested in a faceless state, it WILL come true against your wishes even if at first the state seems benevolent and even if they didn't tell you they will do that in the beginning.  I am not a libertarian and I don't oppose taxes but that's far as I will go.  Whatever property we own today (which isn't much to begin with), my father worked hard to earn it and earned it by lawful means.  Nobody has the right to tell my father it is an undeserved privilege and they will take it away from him but that's what communism is in essence.

I think religion and many philosophies fail to see the oneness of it all and that duality is an innate function of the universe just as quantum particles are composed of opposite charges. When individuals, institutions, collective bodies try to separate these aspects and categorize them is when distortion of reality occurs and ultimate entropy that leads to dystopia until the universal forces balance them again
