Here's what I read:
Pop culture has a possibly unfortunate habit of co-opting Nazism as an all-purpose source of villains. Because it assumes everyone understands why Nazism is evil, our culture rarely provides any historical context for its Nazi villains. Worse, to heighten drama, our all-purpose villains must be made continuously more intimidating and powerful.
The problem is that you're now left with a small army of generic bad-ass villains. Without the context of what it truly meant for a world power to be actively genocidal, those bad-ass Nazi villains can end up as figures for emulation or admiration or respect, for the same reason we put bad-ass villains on heavy metal album covers or use them as team mascots.
So the value of a title like Wolfenstein: The New Order is that it actually takes the time to try to break the cycle of "Nazi As Bad-Ass Signifier".
I don't know how important this point is, but it seems valid and worth thinking about; or, at least, I'd never thought about it before.
