The opposite is kind of weird too. My late Jewish father was absolutely obsessed with the Holocaust. He had virtually every book ever written on the subject. There was a room in the house my mother and I called (much to his chagrin) 'The Holocaust Room' because of the vast number of books on the Holocaust there were inside it.
He did have sort of a reason for his obsession. He was in London from age 7 on through the war because his parents didn't evacuate him and he spend the years 1939-1945 waiting for the Nazis to invade and put him in a concentration camp. So it made sense to me, but it was still going pretty overboard.
He saw Shoah more than once. It's 566 minutes long.
