I don't like this, because I like Tarantino.
Both Wasson and the anons are getting it wrong for two different reasons. The anons don't like the treatment of the Nazi's, Wasson applauds the Basterds.
The movie is a critique of WWII propaganda pieces. The German pictured here is supposed to be a sympathetic — and even heroic — character. The anons complaining about how much they hate the film because they don't like the Nazi's as bad guys and Wasson glorying this scene have completely missed the point.
The bear Jew points to one of his medals and asks what it was for. "Bravery," he replies. The rest of the scene, he stares resolutely into the eyes of the Bear Jew while he bashes his skull. This is a noble death.
Tarantino tricks viewers throughout the entire movie by setting up a villain American audiences have become accustomed to watching get defeated, making you cheer all along the way for the good guys, but he makes the heroes amoral, calloused, and cruel. You are still meant to root for them.
The end of the movie (spoilers) Hitler and the Nazi party are in a theater watching a Nazi war propaganda piece that depicts the relentless slaughter of allied soldiers, where Hitler and the Nazi's are seen laughing, hollering, and applauding throughout. This is you, the audience. You have been applauding throughout the movie at the violence and barbarity of the Basterds entire film, including when a man depicted as noble gets his head bashed in. You applauded, showing your own propensity for believing propaganda.
There is so much Tarantino does to parallel the Nazi's with the American archetypical hero throughout the film. A few examples: the last scene of the Basterds busting into the theater balcony and shooting the Nazi's down below parallels the Nazi's shooting the Jews under the floor boards in the opening scene (one of those Jews who escaped, Shosanna, owns the theater and plotted to kill Hitler at this viewing). The mark of the Swastika on the Nazi's heads is meant to parallel the mark on Jews in the concentration camps. Even the main protagonist, Brad Pitt, who is part Apache, has a rope burn around his neck, showing the dehumanization of Indians in America, but his penchant for taking Nazi's scalps is a parallel to Americans taking the scalps of Apaches. Yet you view the Americans as heroes while ignoring their racism, but condemn the Nazi's for their racism.
The point is that you will cheer for brutality, cruelty, and death of your enemies if you dehumanize them as the Nazi's dehumanized their enemies. It's meant to show that you are not different from the worst villain, you are a depraved human being.
All around poor understanding on everyone's part. Perhaps one benefit is you can all watch that movie with a renewed appreciation for it, regardless of whether you disagree with the overall point.
