There were (and maybe still are) indeed also communist fanatics - but the common red partisan was not a bloodthirsty killer going after anyone who had private property.
So the alignment with the Nazis of the wealthy and privileged happened way before. I am from germany. We had the same story, the common people all did not turn Nazis overnight, but fear of the communist made them align with the Nazis. And the rest is history. I am no expert on concrete romanian or slovenian history. But what I know sounds pretty much the same what I know from german history where I have also first hand accounts. And I strongly disagree to that excuse. The bourgeois did had a choice and it was NOT just between communist or faschism. But they eventually did choose one side - and bear the responsibility. They did fought for a faschist europe, with all implications.
