I didn't care for it. Yes, of course there are people that go too far in promoting a liberal agenda, just as there are people that go to far in promoting a right wing agenda. To point out the excesses of the fringe is easy to do, but at the same time these obvious examples of absurd ideologies are not usually representative of either side. It's great for comedy, not so great for trying to bridge differences.
When you hold up examples of people that got carried away by a concept you take the easy way out to put down those whose ideas differ from you and do nothing to advance political discourse. Most people are neither to the far right or to the far left, but somewhere to the left or right of middle. I would rather see the discussion start there, then work on finding common ground. Then people might learn something instead of getting defensive and shutting down.
