The only problem is that real liberals aren't as funny, nor as interesting as the Seinfeld characters.
While the author has some interesting points, he misses the big picture--the Seinfeld characters are setup to be MOCKED for their shallow, hypocritical values. I have never seen Seinfeld as a tribute to liberalism; indeed, it demonstrates that conservative values are a bedrock for our society and that deviation therein leads to a warp, depraved, narcissistic(sp?), and self-indulgent existence.
