One "problem" is today we're at a point where we're FORCED to include every single possible ethnicity, sexuality, creed, background, all but religion in every single new show, movie, mini-series, etc.
Now, I'm all for being all-inclusive myself, but to the point where it's forced (and I mean forced) just to make sure no group is offended is just another example of how politically correct this society has become; I believe in this day and age, it's actually an FCC regulation that each new prime-time series include at least one African-American regular and at least one Mexican-American regular, otherwise, the show will be considered "racist" and "exclusive".
As for sexuality on television, that's more-or-less a gimmick to boost ratings. Seriously. Every single new show on television these days has at least one episode where two of the hot female leads will make out with each other for nothinbg more than the sake of having the ratings sky-rocket, because let's face it, the television market is mostly male-dominated, and there's nothing better than a man likes to see than two hot dames swapping spit. I say sarcastically.
But it's true, we really have gotten to a point where two guys can't be pallin' around with each other without somehow giving off the impression that they're gay, but that's because things are different than, say, 40 years ago, when people DIDN'T come out of the closet, because gays weren't as accepted back then as they are now... I know sadly that in some parts, people still don't accept gays, but you have to admit, a lot more people do accept them these days than they did in the old days. And sometimes it's hard to tell as well, because the stereotype that all gay men dress and speak effeminitly doesn't apply to all gay men in real life, there's a surprising number of men out there whom you never would have guessed were gay, like David Ogden Stier (who came out a couple of years ago).
I hope what I said made sense, I get the feeling I said something wrong in there somewhere, but I hope I didn't...
