I don't get why you want to rewrite history, std. It happened a long time ago, they have it, who cares? It won't change anything or magically fix it. Art belongs to the people, not countries.
So no, I don't think we should listen to George Clooney (who South Park heavily made fun of for his smug speech at the Oscar's or w/e).
Hitler was going to destroy the art or rewrite history so it was pertinent that the art was freed because it deserved to be held by the people, not a dictator. Britain is going to do no such thing so the art is safe which is all that really matters.
Also, a lot of your topics turn into, "Oh, you guys are just being the internet." Where do you hang out on the internet? I only ask because this place is the friendliest I've ever been to and I don't get why you have issues with this place.
