Gosh. I think you just got me on board the Joss Fails at Racial Sensitivity train. All very, very valid points. Particularly that bit about how Dollhouses sexually victimizes yet another Asian girl. Also, I can't believe the fact that we never see anyone of Asian descent in Firefly, considering how much it's supposed to be a West meets East future vision, never even occurred to me. Don't I feel dense, now?

I will say that there is one thing that I think Joss does admirably on when it comes to race issues, and that's interracial romantic relationships. While mainstream media appears to be getting better on making non-white people the center of their shows/movies/commercials, they still all SUCK at portraying positive interracial relationships. I think that America still seems to have a problem with this issue. I'm kind of convinced that if Michelle Obama was a white woman, that Barack would never have won the presidency. So I do think that this is one way in which Joss kind of excels. To break it down:

Buffy: Giles/Olivia, Buffy/Robin, Faith/Robin, Xander/One of the Slayers from the comics who's name I can't remember...
Angel: Gunn/Fred
Firefly: Zoe/Wash (One of my most favorite couples ever, PS)
Dollhouse: Sierra/Victor, Boyd/Whiskey (From what I saw during Epitaph One)
