Far right attacks on a Holocaust survivor

After Media Matters has noted that David Horowitz's and Richard Poe's attack on George Soros is an unsourced smear, Poe issued this reply:

When the Nazis came in 1944, Soros’ father saved the family by splitting them up, providing them with false identities and bribing Hungarian Christians to take them in. Young Soros posed as the godson of a man named Baumbach, an official of Hungary’s fascist government.

In an April 15, 1993 interview on the PBS television show Adam Smith’s Money World, Soros explained that Baumbach’s “job was to take over Jewish properties, so I actually went with him and we took possession of these large estates. That was my identity. So it’s a strange, very strange life. I was 14 years old at the time.” (2) Connie Bruck, who interviewed Soros for The New Yorker in 1995, wrote that, “he posed as the son of a Hungarian government official, sometimes accompanying the official as he delivered deportation notices to Jews, or took possession of property owned by them.” (3)

So merely accompanying this person made a Nazi collaborator out of a 14-years old Jewish boy? (It's not as if he could have "helped" to take over the estates in any meaningful way.) Mind boggles. Or take this:

The choices facing young Soros were grim, but they were choices nonetheless. “Granted, Soros was only a teenager when he faced these trials, yet boys his age were fighting and dying all over Europe,” we wrote in The Shadow Party. (5) Indeed, boys as young as Soros commonly served in those years in underground resistance movements and partisan bands from icy Norway to sunbaked Crete. That path was open to Soros, if he chose it.

Where have I seen this before? Here:

I didn't know that Anne Frank's father, Otto, was a Nazi collaborator and war profiteer.

[...]

Collaboration was a norm, though admittedly not for everyone. In the Netherlands, for instance, only 80% of Dutch businessmen collaborated with the Nazis. In the camps nearly all Jews whom the Nazis chose to work for them themselves chose to collaborate with the Nazis. It was the norm. There were some who chose not to collaborate. Same as with the Dutch businessmen.
