WWII and the Nazis just don't carry the weight for younger generations. It's just something that happened a long time ago, far away. It has about as much relevance for them as the Boer war did/does for me other than it's a bit better documented with some videos of a guy with a funny mustache. And that's not a judgement, it's just the way the world moves forward. They make the comparison because they don't know how invalid it is.
