An unforgettable trip (--about the history)

I just watched a film which it named "Schindler's list". The film was shot in memory of those Jews who were killed by the German, about six million Jews. i don't imagine that had such a great number of Jews were killed. it was reminded me of my Krakow trip, when i visited the Auschwitz Concentration Camp, i did't believe that i saw terrible things, rows of wooded house, it were very big, crude and simple, like the stable. i did't imagine that how did the people live, but untill i watched this film i konw that the war was terrible and sometimes the people was terrible too, but the life of people wes not important, a bullet, a shot, a pool of blood...
i was very sad after i watched the film, although that war have finished for a long time but the racial discrimination issue still remained, i hope that one day all of the people in the world will become a big family, without the war, without the discrimination, without the suffering... just have happiness!
