The character of Brian the Dog on Family Guy is not only supposed to be the proxy for the shows writers and viewers, he is also the archetypal leftist douchebag, complete with a Dennis Kucinich for President bumper sticker on the back of his Prius. Consider the facts
* Unemployed, Brian sponges off the family of a gainfully-employed, working class father figure
yet considers himself superior to him.
His biggest ambition is to bang the wife of his best friend
the same fellow who feeds, clothes, and shelters him.
* A pseudo-intellectual atheist college drop-out, he considers himself intellectually superior to those around him solely on his ability to mouth the proper set of left-wing pieties.
* He has a substance abuse problem, he self-medicates with alcohol and cocaine. (In a DVD commentary, the shows creators explain that his substance abuse stems from his need to cope with the intellectual inferiority of those around him.)
* While protesting that he votes Democrat, he is in fact a closet racist who reflexively hates blacks (as seen in Dont Make Me Over and Chick Cancer.)
* Though he fancies himself an author, his only success has come from directing porn and plagiarism. Even Lois finds his writing hackneyed and stilted.
* Though he ostensibly supports gay marriage, insinuating the homosexuality of others, especially Stewie Griffin, is his favorite put-down; thus indicating the low esteem in which he holds homosexuals.
The writers and producers of Family Guy who seemingly expend every other manatee joke these days bashing Bush, conservatives, America, or some other guaranteed head-tilty applause line have unintentionally created a character that really shows the shallowness and depravity that typifies the modern left.
