Short answer as duties calll..
Ah I see. Your argument is that they cannot be socialists because they were also other things, and you assume I am saying they are only socialist?
I am saying they are many things, including socialist, and that being other things as well does not preclude them from also being socialists. Even not getting with other socialists...as others have humourously and accurately pointed out, does not preclude them from being socialist (Galilean people's front etc...)
You are clearly well studied on it, but I feel your comments carry a bias, the Volk nationalist thing for instance...does nationalism automatically preclude socialism? Does nationalism automatically preclude class based division? What if a ruling or moneyed class can be seen as essentially a different nation? (This was part of the method used to stir hatred against the Jews after all, historically.....it's part of the class argument in Britain too, after all, it's still essentially a Norman aristocracy, even across Europe. Your average left wing Nationalist nutter will happily decry the queen for being German as he cries for revolution and republic and recompense. Magna Carta! Did she die in vain?) what is bringing the means of production into the ownership of the people, the great socialist or Marxist or something dream, if not almost identical to all of the Nazis various Volk industries. Volk just means 'the people' does it not?
Some socialists are evil nasty buggers. Not all evil nasty buggers are socialists. The same is true on the other end of the political spectrum, as others have said, it's the extremes you have to worry about...to which I would add, the phrase 'oh he couldn't! He's one of us...' has no doubt been uttered every time a group takes its eye off the ball and assumes their own ideology to be above reproach, and the phrase 'oh well..he wasn't really one us you know....' usually follows in short order after something nasty has reared its head.
