• About protected classes. Being gay, black, latino, etc... these are not religions or philosophies. Judaism, Christianity, Islam, and Hindu are the major religions of the world. Buddhism is arguably a religion as practiced by some, a philosophy as practiced by others. So you need to compare apples and apples. You don't criticize a writer for attacking what a person thinks by pointing to one who attacks what a person is. It doesn't make sense for example, to say, "They portray Muslims as terrorists all the time, but you never see them portray an Eskimo as a terrorist."
• The path to representation on TV is pretty well established. I haven't charted it in some time, but if you will think back to the rise of blacks on TV you have to go through these stages, not necessarily in this order:
1- background - servants extras
2- talking servants
3- funny talking servants
4- smart mouthed talking servants
5- servants with hidden talents, often covering for the boss behind the scenes
6- servant with a criminal association
7- whore with a heart of gold
8- criminal who dies in a noble act
9- comedic lead
10- dramatic lead
11- romantic lead
12- somewhat normal
13- treated like crap like everyone else
Americans can say what we like about Christians, because the overwhelming majority of us are culturally Christian. You can't claim that this is a Christian nation, and then say that the only members of the club are the ones YOU consider to be Christian. Christmas Christians are the bulk of the nation. We own the subject matter, and we can say what we like about it.
As for gay characters, yes you do see them on TV as bitchy men, butch women, drag queens, and every other stereotype. Yes, gay characters have been following the chart more or less, but we're also something of a special case in Hollywood because that's where a lot of gay people found refuge from a bigoted and discriminatory hometown America.
I find it amusing when people complain about entertainment. This is a business which has been considered beneath "decent people" since its beginnings. Mel Brooks said, Without Jews, fags, and gypsies, there is no theater.” There was a reason for that, and for "decent people" to now complain that they aren't running things is funny.
