I ponder it all the time...problem is that the left wants to teach revisionist history not all of history. They want to rewrite history by removing statues (good and bad) that remind us of where we came from and how painful it was to get past that. They want to remove the brutality of war from Civil War/WW1/WW2/Korea/Vietnam and now Desert Storm and Desert shield. Those wars and why they were fought aren't studied anymore. We don't teach Civil War and how brutal it was or why it was fought...yes slavery main cause but other factors. We don't teach the brutality of Hitler and the Holocaust hence why we have so much anti semite atmosphere in our country now. If you asked High School kids today about any of those I bet you would get the glassed over look as they are googling it on their phones. My thing is if we teach history then teach it all...don't pick and choose what fits an agenda...teach it all in it's glory or its horror so people remember how truly bad it was or how truly remarkable we were.

Doesn't say much for those who simply remove it and rename institutions, facilities, cities, bases, etc...

Those who rewrite history are insuring we repeat it
