Expat Expectations - The Pissing Contest at the Great Wall

Given the length of the Great Wall, it's inevitable that huge sections of it are unpatrolled but easily accessible. What does your average western expat do in this situation? Throw a rave, of course! There are plenty of "illegal" parties in China and a few of them inevitably end up at the biggest, baddest wall around.
Some time ago, this issue eruptd in controversy because someone published a photo of an expat urinating on the Wall during a party. Howls of protest erupted at the audacity of the expats and their lack of respect for one of China's great cultural treasures. My knee-jerk reaction was the same. I mean, why piss on the Wall when there's plenty of open ground around the area?
Upon reflection, though, it's a very silly thing for the locals to be upset about. For one thing, I wonder if anyone complaining about the expat-pissing incident has actually _walked_ the Great Wall. The whole things smells like one big urinal. Almost every secluded corner has been used as a bathroom (and from the stench, it's recent). Since there are many more local Chinese at the Great Wall then expats, one would have to assume that it's the Chinese who are actually pissing all over the Great Wall.
We could take the arguemnt one step further. Why does the Great Wall look the way it does now? Why is it so dilapated and run down? The main reason is not the weather and the elements. With the loss of control by the imperial government, a lot of Chinese peasants realized that there was a huge Wall of pre-cut and shaped stones that were ripe for plundering for their own uses down on the farm.
While you won't find me pissing on the Great Wall anytime soon, it's probably a good idea to put things in perspective before blaming the expats for the degradation of Chinese cultural artifacts. It probably wouldn't hurt the government to put in a few more bathrooms along the Great Wall as well.
