Ms Palin is a symbol of deep American introversion, of the fact that you have ceased to take yourselves seriously and, more important, don't much care who knows it. Arguments over the relationship between the wider world and your choices have become irrelevant. You have detached yourself, finally, from the global community. This is isolationism as never before conceived. "American" in my life has been lingua franca, for better or ill. Now you talk to yourself.
And you talk, my friends, in the sort of gibberish that once you spurned. It's not about Ms Palin, as such. It is about the process that creates a candidate-grin manipulated to serve darkness, ignorance, fear, a war economy, and the flaunting of stupidity.
