Isn't Socialism being let off of serious analysis when it is not submitted to reality analysis with the real-life application for 30 years under Stalin?

Well, how about a comparison with Norway? Advocates of Socialism have an argument its worked pretty well there. (Though there are counter arguments!) Believe me when I tell you I’m no fan of Socialism, i.e., a capitalist through & through. However, when dealing with any Socio-economic system of government you encounter a prodigious number of variables – overwhelming in my view – to reduce that system’s ‘essence’ to anything sufficiently ‘micro’ that can enjoin or entertain the possible label of a logical fallacy.

The eternal lament of the Socialist, somewhat analogous to yesteryear's Brooklyn Dodger fans’ “Wait ‘til Next Year!” runs along the lines of “Just wait, eventually we’ll get it right!” But despite minor setbacks such as the Soviet Union, Red China, Cuba and most recently (& conspicuously) Venezuela, there exists the theoretical possibility this could happen (i.e., however ‘right’ is defined) thus evoking comparisons with prior ‘failures’ do not connote logical fallacies, especially since opponents can always argue “you are comparing apples with tricycles!”
