Is the American left becoming isolationist as it stiffens its anti-globalization stance?

I think it is. When I was a kid, the
right used to taunt the left as fuzzy-thinking one-worlders. Even into the
1970s, John Lennon advised people to think globally and
act locally.

But the left is not down with
globalization anymore. And that means it may be drifting into
isolationism. 

If you're into tracking American
culture, one of the great, sober, leftish events in the United States is the
annual gathering of Maine organic farmers. This isn't California-style Burning Man self-indulgence. Rather, these are hard-working people (you try growing stuff in a state with a
six-month-long winter -- and then, when you thaw out, be swarmed for five
months by no-see-'ems, black flies, deer flies, and mosquitoes the size of
Blackburnian warblers). Modern Puritans, if you will. I mention this because this
year, one of the events at their big annual fair is anti-globalization storytelling.
