I don't disagree with you but...

So were they the in-group or not? Most people in occupied Europe did not approve at all of nazi germany. Sure, there were some collaborationist but most europeans did totally disapprove nazi germany.
It's not the same as people who voted for communism then got was they asked for: in my opinion, when you vote for a totalitarian society, it's just fair game that in return you get what you asked for (I know, I know, the ultra-left leaning are going to say that "this wasn't true communism and next time, believe us, we're going to make it work").
You cannot compare occupied Europe who didn't ask to live under a totalitarian society to those who supported communism.
