The fact that Berman (or perhaps Braga, someone will have to correct me) couldn't keep the character's ethnicity straight (according to Garret Wang) doesn't suggest much thought going into the character in the first place. Reads like tokenism to me.
Looking back on it there were a few things that bothered me about berman team.
One, Chakotay was kind of generically native american...or south american...I can't even say which because he was so generic. "Acuchi moya"-----what does that even mean? And why does he say it before almost EVERY ritual? Were they all the same ritual or something? His character seemed kinda racist because it displayed little knowlege of his "race", whichever one that was.
Two, Kim's character was supposed to be Korean, yet he wasn't Korean at all. They never explored his culture, and couldn't keep his ethnicity straight according to him. That seems kinda racist too, because it displays an ignorance to it.
Three, to attain ratings, they threw in a woman in a catsuit without throwing in a hot guy who seemingly gets shirtless in episodes. That gender preference in and of itself is sexist, and I think the basis behind 7's character is a little sexist itself considering the first few episodes men oogled her like an object. That said though she ended up being one of my favorite characters thanks to the great acting of Jeri Ryan.
Four, no gays when there could've been. It was 1995, not 1985. There were and had been shows and movies that were successful with gay characters on them. I'm not going into this much more considering in the thread "Voyager, what would've you done differently", I went into it in detail, so reference that if you're interested. But that decision, or fear even, seems a tad homophobic.
And five, it was also sexist to have to alter Janeway's hair style to make her more "appealing". There was an article where Kate Mulgrew said that she wished instead of changing her hair style to make her more appealing they focused on her character instead. And I have to say I 100% agree. If she's not appealing, chances are it's something deeper than a stupid hair style.
Star Trek really dropped the ball on integrity, as much as I love and still love it, towards the end. I mean come on, I've never seen a character with such an OBVIOUS boob job like T'Pol.
