OP is using piss pour examples. Do we know anything about Audrey Hepburn aside from her being a pretty, talented actress?
I could list porn stars who have more class than Kesha (or Ke$sha, or whatever stupid bullshit), but instead I'll simply mention Karen O (singer for the Yeah Yeah Yeahs), Michelle Obama and Tina Fey, Jenny Lewis (singer for the Watson Twins and Rilo Kiley), Diablo Cody (writer/creator of Juno and United States of Tara), and Scarlett Johannsen (actress who did an album of Tom Waits covers, who despite recent Escapist rumors most definitely does NOT have a penis

).

Jenny Lewis
Speaking of Tom Waits, let's have a look at the guy.

He's made dozens and dozens of albums, literally every one of them bad-ass.
So I'm not sure what you're getting at here, but your view is not an informed one. All of the female divas are going hyper-sexual (or were the last time I watched The Soup), which is a normal trend amongst the marginally talented. No biggie. It doesn't mean they represent women, because they don't. Nursing is still very much a female dominated field, and nurses by and large are not gutter tras-
You fell asleep, didn't you? OK, well, then here's a pic of singer/songwriter Janelle Monae.

Not exactly a gutterslut, is she?
As for gay men, here's Jesse Tyler Ferguson, real life and fictional gay man and star of Modern Family.

Not exactly Adam Lambert. Speaking of Modern Family, here's ugly-ass, skanky Sofia Vergara

The slut!
So yeah, I don't think your juxtopositions mean anything. The spotlight is hogged by the likes of the cast of Jersey Shore, yet I don't see any threads on here asking "What happened to Jersey-ites?" because there have always been douchebags from Jersey and they've always been a minority (though the spray-on tan and vocal affinity for genital-shrinking HGH is relatively new). This is just another example of the
things are worse than they used to be myth. I'm guessing you weren't around when Hepburn was alive and in the spotlight. Hell, you may have not even been around at the time of Freddy Mercury's death. So how 'bout we all agree to stop pining for an era that really wasn't as great as we think it was, especially for women, minorities, immigrants, children and gay people, and instead try to make our time a better one?
