And how many Romanians, Bulgarians, or Hugarians were raped? Also, you're tailing to account for the fact that the Nazis did just as much raping when they drove their way across Russia.
Like I've repeatedly said, yes, those individuals committed what we consider to be war crimes, but when you look at both sides as a whole, one side clearly engaged in much worse. As someone who has Red Army veterans in his family, their entire ethos was that this was justified retribution for what was done to them and their families. Even with this indignation, as a whole they still committed less heinous shit than their enemies did. Their actions shouldn't be tolerated in a normal society, but it should never be equated with what horrific shit their enemies did.
