It doesn’t really stand up to scrutiny, though; genocides have been committed from everything from borderline failed states to states that appeared a lot more functional than Nazi Germany (which really wasn’t all that ordered).
Now if you were writing an article about German engineering, I would be mildly surprised if there was no reference to their rocket program in WWII. But given the topic, I think that wouldn't leave the same negative taste in my mouth.
From my experience, Germans tend to do what they're told without questioning.
They will happily line up at an empty street and wait for the light to turn green, and they get really upset if you mention the Holocaust; because those are the rules.
I have no trouble seeing how these traits contributed to what happened.
Every aspect of German culture can be linked to WW2 without much effort and has been for decades. Here is a humorous look at this https://www.youtube.com/watch?v=MfFxoyxQAh4 instead of a sarcastic wikipedia link.
I do understand where you are coming from but sometimes you just have to let it go, as most others have done. WW2 ended in Germany over 75 years ago, people don't want to be reminded of it underneath a fun travel blog.
