Sorry, can't edit anymore. That said, I believe the title itself is flamebait - you don't need to be an expert in WWII to see that. It is not a question of who suffers most, just historical facts about where the war took place and who fought in it.

Just look at the summary and maps here https://en.wikipedia.org/wiki/Eastern_Front_(World_War_II) and tell me again that I am the one nationalism baiting by pushing back against the term "Russo-German war".

But you are correct that I cant assume bad faith by the original authors. There might be other reasons.

You have a point, but the art of commenting well here involves resisting the effects of provocation. If you react to provocation with more provocation, others do the same and we get flamewars. I know it's not easy to avoid (for me either) but we all need to work on this in order to have a shared space that's a bit better than internet default.
