I've spoken to enough haredim over the years to assure you that they are as aware of the Holocaust as anyone. They ask the same questions we all do, but perhaps emphasize different aspects (such as the haredi efforts to rescue Jews, or halachic issues related to the Holocaust). In any case, all efforts to preserve memories are welcome.
