As a cartoon fan who is gay, I'd like to see more gay characters in American animation, particularly ones that're more well-rounded.... when gays appear at *all* in animation (basically only in adult-oriented cartoons---"gays aren't suitable for children!!!"), they tend to be portrayed in ways one haven't seen in live-action productions since the 70s, i.e. either as closeted or some sort of (usually effeminiate/flamboyant) stereotype. If live-action in 2010 can now portray gays as talk show hosts, lead characters in sitcoms and dramas, etc., I'd like to think American animation can do better than Smithers and Big Gay Al by this point.
And no, "this character is, you know, nudge-nudge, wink-wink, look-the-other-way-Fred Phelps-types" doesn't cut it... if a character's gay, they should be portrayed as openly such, and also as wacky/butt-kicking/etc. just like everyone else in said production (i.e. if it's a superhero show, they're probably taking part in the action like everyone else, or if it's some show about teens in high school, a plot might be "Archie and Jughead try to help Kevin prepare for his date with John in time for the Riverdale prom, but being Archie, wacky hijinks ensue.").
