Well, first I would like to start with: you put your reply inside of the quotation. Second, yes: this is a place for discussion, where you can state your own personal beliefs or ideas. MY personal belief, for example, is that expecting a comedic television show to show every side of every human that's ever existed so that you don't get your panties in a bunch is dumb. That's my idea.
Comedic relief? You understand that the show is a comedy, right? ALL OF THE CHARACTERS ARE THERE FOR COMEDIC RELIEF. THEY ARE DESIGNED TO BE FUNNY; THAT'S THE WHOLE POINT.
There are plenty of movies and TV shows that present the "diversity" of the gay community. Tonight's Glee episode, for example (which I have yet to watch), will introduce a new gay character that is pretty much a stereotypical jock straight guy, the only difference being he likes penis. There was also Karofsky, who is not only very straight acting but represents a huge part of the gay community: the homophobes that can't admit their sexuality to themselves yet.
There's also a fantastic show on Showtimes called Shameless, which is based on the original UK version of the same name. In that show there are four different gay characters (thus far). You have the ginger, who is in ROTC; there's his arch-nemesis turned lover, who is nothing like the stereotypical bottom; the Muslim man who owns the gas station; and the slutty girl that has sex with everything that moves including her boyfriend's father.
That's just two shows right off the top of my head that have many different gay characters with different personalities that rarely if ever meet the stereotype.
You're just either not looking hard enough, or are only paying attention to the ones that do meet the stereotype, in which case you're just as guilty as hollywood.
