OK- Lets all take a deep breath and calm down.
The show is written by a bunch of pro enviromentalist leftys. With the exception of Flanders and Burns there are no right wingish characters on the show, and Burns is basically the devil.
For anyone who watches the show, this is nonsense. If anything the show is overwhelming pro left, and depsite the fact its on FOX, the writers take shots at FOX every chance they get. Its the same thing with Futurama which also overhwlemingly leftist ( its still my favorite cartoon ever though).
I'm not complaining about the show- Its one of my all time favorites, but right wing? Not a chance.
Theres a pretty good book out about the Simpsons that any fan should read. Its called the Philsophy of the Simpsons- or something like that. All the chapters are written by Philsophy professors who watch the show. Interesting stuff.
