Armenian Genocide
From iGeek
Of course, an entire religion/culture shouldn't ONLY be remembered for their worst acts. But their worst acts shouldn't be forgotten either. And if they refuse to acknowledge it, then they need to be reminded of it even more. The Islamic Turks exterminate 1.5 million Christian Armenians and 300K Assyrians, and Islamic intolerance/tribalism was at the heart of the reasons. So the Christians had the Spanish Inquisition with 2K executed for heresy as recent as the 1700's. And the Muslims have a couple million, at the turn of the 20th century.
