Theres a reason folks are not using that word, and it has to do with it being a legal definition at the UN.
Proclamation 4838 of April 22, 1981
Days of Remembrance of Victims of the Holocaust by the President of the United States of America
The Congress of the United States established the United States Holocaust Memorial Council to create a living memorial to the victims of the Nazi Holocaust. Its purpose: So mankind will never lose memory of that terrible moment in time when the awful specter of death camps stained the history of our world.
When America and its allies liberated those haunting places of terror and sick destructiveness, the world came to a vivid and tragic understanding of the evil it faced in those years of the Second World War. Each of those names Auschwitz, Buchenwald, Dachau, Treblinka and so many others became synonymous with horror.
The millions of death, the gas chambers, the inhuman crematoria, and the thousands of people who somehow survived with lifetime scars are all now part of the conscience of history. Forever must we remember just how precious is civilization, how important is liberty, and how heroic is the human spirit.
Like the genocide of the Armenians before it, and the genocide of the Cambodians which followed it and like too many other such persecutions of too many other peoples the lessons of the Holocaust must never be forgotten.
