"Why is there nothing about how men are portrayed as buffoons, or as the comical sidekicks to the competent, capable woman? Why is 'The King Of Queens' style male persona so acceptable (fat, slightly left of the bell curve, somewhat funny, and exceptionally ignorant) while the wife in almost every single sitcom (even in cartoons like the Simpsons and Family Guy) is always the 'smart one', correcting his world view, and fixing all of his mistakes?"
People watch those shows for the funny characters. The female characters in those shows may be more intelligent, but they don't drive the comedy and, just as often as they are treated as the rational one, they are portrayed as the nagging, overbearing character. A character like Homer Simpson might be a fat baffoon but he at least he has a fleshed out character. Whenever I see a fat, female comedic character, they are almost always a very sassy walking fat joke with absolutely no depth to them, whatsoever. Nobody watches these shows for the main characters' wives.
Stupid characters drive most comedy. All you are saying when you complain that women are the smarter characters in comedy is that there aren't many female-lead comedies. And, when you talk about why there are more fat men on TV than fat women, you are actually drawing attention to the fact that it is really hard for any woman who isn't sexy to get work in TV or film.
There are plenty of male characters, in fact, the vast majority of male characters in the media are not fat baffoons, only in comedy is that the case. I don't recall a stupid fat guy starring in any of the action movies I watch, or lots of dumb guys getting outsmarted by their female counterparts in science fiction.
Tell me how many knuckle dragging incompetent male characters star in CSI?
If your only example of males being degraded in the media is stupid comedic characters, usually written by male comic writers, often as a platform for the comedian/comic actor playing them or even themselves (a lot of sitcoms and comedy films are co-written by the lead actor or written specifically for said actor), you're really not making yourself seem all that sympathetic.
I don't even consider myself a feminist and, honestly, I do think sexism, in general, is more of a two-way street than a lot of people are willing to accept but that was just a dumb argument, through and through.
