Nobody is saying to erase history. Germany didn’t erase history of WWII or the holocaust. They took down statues, pictures, monuments, and the like, of Hitler, though. They made naming your kid Adolf and the Nazi salute illegal, too. You do not honor the bastards of history. You honor the fallen victims. You do not support the language or customs of those who would oppress the victims. You help the oppressed regain and remember their own, unjustly taken, mocked, and made cause for punishment.
Do not HONOR the oppressors. Teach of them, so they are not forgotten. Put them in the history books, to be sure. To ignore history is to repeat its mistakes. Build monuments to those who still suffer to this day. Those who have lost their culture and had it crushed and destroyed. This is not such a tough concept.
