Serious question: if you're white, why would you want to see a non-white person on your TV more than a white person?
To see something I'm not like super personally familiar with? I can see plenty of white people with hollywood-esque six packs that make me feel inadequate enough (
) but a diverse cast or makeup for a show is more interesting to watch. I mean, i have problems with how 5-0 treats torture and how fucking seriously it takes itself anyway...and how someone goes from a villain in the Yakuza to husband etc....buuuut Steve and Dano are not that interesting as characters.
I think also its about contextual believably. For a show set in Hawaii to not have any asian or hawaiin leads, it feels weird. Like they are peripheral characters in a show that uses the islands as a character and has lovely shots on the environment...conversely it doesn't make sense to me in something like Doctor Who when the new showrunner says they think a Black/Female Doctor would be gimmicky, like it's already established that the Doctor regenerates into "faces" he recognizes and that the Time Lords are gender/racially-fluid...
So for it to eternally be white men feels boring. It can depend on what type of show you are watching, too....like I got bored with TWD fairly quickly but I was curious that for a while T-Dog (?) seemed to avoid being the token black guy in a horror movie trope.
