Great review of the new South Park book which casts the series as an answer to the obligatory leftism we’ve been inundated with for the last three decades. Here’s a great quote:

Last year, James Pierson of the WeeklyStandard.com coined a term called “punitive liberalism” to describe the post-1972 Left’s belief that America was always on the wrong side of the key events in history, and therefore deserved to be punished. It was a worldview very different from the older, pro-American FDR/JFK-style of liberalism of the previous generation. It first began to be noticed in shows like M*A*S*H, where Alan Alda’s Hawkeye could find little difference between America and the communist North Koreans and Chinese. By the mid-1990s, when he wasn’t producing cartoons pushing radical environmentalism, Ted Turner commissioned a history of the Cold War for CNN, and its producer was quoted as saying that Turner demanded that the documentary series deal with the Cold War “unjingoistically,” adding that Turner “did not want a triumphalist approach”. In other words, Turner didn’t want to emphasize why it was a good thing that America had won.
