I don't understand this attitude. We've had almost a century of historical experience with socialism. It isn't as if we're back in Marx's time when the Paris Commune was the only experiment in proletarian revolution.
I mean, are you guys seriously arguing that all the millions who struggled, fought, and died for socialism in the 20th century, suffered in vain because there's absolutely nothing we can learn from their experience about what socialism is and how it would work? Amazing.
