According to our history books, whether true or false, the 'Allies' where the first to walk into the concentration camps. The proof, if there is any, must therefore be found ind the documents of the Allies.
In my opinion, the reason Q brought up Nazi issue because what is happening today has 'some' of its roots in Nazi time. Therefore, what we should be doing is finding that connection. We know ANTIFA has its roots in Nazi time time but when I researched that I found that ANTIFA were actually communists and not Nazis. More important than anything is that all of a sudden this group ANTIFA is reborn again with the same flag an same name. That is spoopy.
