Exactly. The Bolshevik-Socialists neatly twisted the abhorrent racial Socialism of the National Socialists into something more evil than the actual nature of both movements.
Socialism equals collectivism equals enemies equals murder. Simple paradigm. If you support Socialism as an ideology and ultimate goal, you must therefore support the elimination of either so called racial enemies or economic ones, which can also be "nationalities".
Ill put it in the boldest terms: There is no difference between a Socialist and a Nazi except in the name of the enemy.
