I’m looking for serious replies only, please. I have a friend whose family ‘escaped’ from East Germany and moved to the US during the Cold War. My friend’s opposition to socialism seems to be almost exclusively based upon this idea that their poor family had to ‘run from evil communists’. This person either doesn’t know or won’t tell me what their family was up to in Germany from 1930-1945. I suspect they were nazis and were not ‘escaping’ socialism but hiding their participation in war crimes by moving to a country that would not persecute them for killing civilians etc. I know their grandfather’s name (who was just a boy when his parents forcibly moved them all to the US). How would I go about proving my hypothesis that they were nazis? Are their databases with the names of nazi party members and so on? Any advice and guidance would be much appreciated. Thanks.
