In my age group of Germans (born 1966) it's basically dogma that our generation is responsible for studying the Holocaust (movies, literature, art in addition to documentaries, etc.) and then turning around and preventing it from happening again. For the most part I think it's been a success but it backfired with a small but steady percentage of people. In addition, Germans can come across as sanctimonious when picking who their favored victim group is, often being accused as being antisemitic when siding with Palestinians, for example.

The other problem was that the discussion basically happened in a vacuum, hardly any of us interacted with Jews. Since I emigrated to the US I've had more productive conversations with actual victims, or rather their children.
