I understand underlying anger; what is social geography about except anger explosions, many apparently warranted, but the obliteration of historic treasures is unadulterated assholeness on top of obliteration of whole peoples. Strange icing. I presume there is history for it, done by many of us, but it is still awful on top of godawful.
I do think people at the top must be for horror for fun.
