The holocaust began with KrystalNacht in 1938 and lasted 1945

The Holocaust is a horror we must remember, ... Preserving memory is a solemn responsibility, aimed at saving men and women from apathy toward evil, if not from evil itself. We must never forget.
William J. Jefferson, Congressman, Louisiana



China had its horrific Culture Revolution from 1966 thru 1976

我們誰都有責任讓子子孫孫,世世代代牢記十年慘痛的教訓。 只有牢記文革的人才能制止歷史的重演,阻止文革的再來。
(巴金)
We have the obligation to our posterity, to all generations to come, to painfully remember the cruel bitter lessons of the last decade. For only with memory of the cultural revolution can we deny its replication in history and prevent its recurrence ever again.
Bajin, Writer



A thought from Dachau

In Germany, they came first for the communists, and I didn't speak up because I wasn't a communist. Then they came for the Jews, and I didn't speak up because I wasn't a Jew. Then they came for the trade unionists but I didn't speak up because I was not a trade unionist. Then they came for the Catholics, and I didn't speak up because I was a Protestant. Then they came for me, and by that time nobody was left to speak up.
