Facebook deleted

I have quite a fractious history with Facebook. I deleted it in January 2010 upon returning from a few months in Paris, and didn't rejoin until last December. Following my return, I made the unpleasant discovery that Facebook seems to have become a forum for juvenile and frankly toxic political ranting. I have found myself drawn into awkward and unpleasant disputes with friends of mine whom I previously considered to be intelligent adult human beings, now somehow transformed by Facebook into the most pathetic kinds of 5th form Marxists. I didn't want to see my friends diminishing themselves like this. And so, about two weeks ago, I quit. I don't think I'll ever go back.
