Did you read the link cited? He visited the property of a landowner who was no longer there.
I have no real qualm if you want to call it cooperation or collaboration. His father purchased phony papers in order to save his family. He was involved, in a tangential and immaterial way, in the horrific machinery of the Holocaust. You are entitled to your thoughts and feelings about that. But you're not entitled to make **** up.
I'm also continually perplexed by your support and admiration for European nationalists who are bargain-bin Nazis who'd try again if given the chance.
First off intake the premise that push cons to shove everyone hates the jews. History has taught us that. So deciphering the ones who hate jews more is not of interest to me even though I see no real evidence of the claims you are making.
Further, just because one is born a jew does not make them beholden to the Jewish people. Meaning, we should not just assume that soros had to 'forced' to collaborate and may have caught the jew killing fever as so many did at that time. That's just speculation as your position on him being forced to collaborate is.
