Holy shit are you baiting me?
Inglorious Basterds has nothing to do with politics Tarantino is all about subverting expectations.
The Nazi officer is presented as civilized and subdued and the Allied soldiers as brutish and barbaric as a role reversal, you are meant to feel uneasy of the treatment and fate of the nazi while also questioning the feelings themselves, "Surely he deserves it?".
The whole point is not to offer a moment of dumb violence and schlock, believe it or not humans don't want to kill each other, this is why all military training includes hazing and other psychological tactics devised to break down these barriers so when the moment comes to kill somebody who you never met you won't hesitate and pull the trigger.
That's the genius of the baseball bat scene from the context the audience expect violence without remorse but Tarantino reverts the expectation and plants a seed of doubt, " Is it disgusting that I feel empathy for a war criminal?".
