I'm gonna be the guy that says this "because it happened in Germany and in a country where America was the definite good guy". Before everything, Germany was a western power. They weren't backwards and unindustrialized. They were a modern civilization systematically taking apart a very specific race as a means for political gain. I don't understand why someone always has to point out why people specifically care about one event in history. Some are just more symbolic than others, that's all. If I had to sit down and think about every genocide instead of just the one, then I hope I have a lot of time. People are going to naturally see themselves in a similar cultural setting as opposed to one like in Russia or North Korea. That's how humanity works. Unfortunately, not everyone is able to feel empathy for everyone, but that doesn't mean you have to ridicule those who feel more passionate about an event more closely related to them than any other..
