How many Holocaust survivors are even left?
A significant portion of the Hasidic Jews in the US are descendants of Holocaust survivors. For example: members of the Satmar dynasty. A significant number of non-Hasidic Jews in the US are descendants of holocaust survivors who immigrated after World War 2. This includes, children of survivors, grandchildren of survivors, and great-grandchildren of survivors. I assure you, the Holocaust remains a very difficult subject for many Jewish families, including mine, and it also affects a lot of Jewish families who weren't directly affected.
"Never Shall I Forget" by Elie Wiesel
Never shall I forget that night, the first night in camp, that turned my life into one long night seven times sealed.
Never shall I forget that smoke.
Never shall I forget the small faces of the children whose bodies I saw transformed into smoke under a silent sky.
Never shall I forget those flames that consumed my faith for ever.
Never shall I forget the nocturnal silence that deprived me for all eternity of the desire to live.
Never shall I forget those moments that murdered my God and my soul and turned my dreams to ashes.
Never shall I forget those things, even were I condemned to live as long as God Himself.
Never.

Also note that the nazis also murdered Romani, Sinti, Poles, Slavs in concentration camps and ghettos. They also murdered and starved the general civillian populations of areas they took over.
"...what also happened to the Polish Christians (and other Slavic peoples) under the Germans - which was another attempted genocide by itself."
