Probably to let it decay and present it as a real time art installation highlighting that everything that it stands for will eventually turn to dust. Restoration it is tantamount to deification.
Well, I get both sides. If you don't learn from the past, you can't define the future. I don't have any issue with statues of CSA people gloring them. It's a bit different. Mostly 'cause lots of rednecks are loke "it's part of my heritage". YOU WERE BORN IN NEBRASKA! As far as I know Auschwitz is still up, and is a memorial. Go to downtowntown Berlin dressed in nazi garb, and do the hail hitler. Your ass would be beaten in minutes! Dawkins interviewed Ted Haggard. He said he spoke like he was at a Nuremberg rally. He didn't know what that was, but said most people would think it's a "rock concert" (his church). lol Any WWII forums on here? I study that a lot.
