(Rant warning)
I was just recently thinking, one of the things that made Star Trek stand out when it first appeared back in the 1960's the crew was full of diversity, including people from every corner of this globe (well . . . except a prominent Latin American (being not Hispanic American but from either South or Central America)) character). Although the lead protagonist was a corn-fed Red blooded American (yes, as in the United States), those who were around this character would not normally be seen in a positive light in those days.
In TNG . . . that continued . . . but expanding the cast to not just Humans for the majority (granted there was Spock, but he was only 1, all be it an important 1), but a mix of non-Earthborn Humans, characters with noticable disabilities, AI Lifeforms, and those not of this Earth and of a different species.
This continued also in DS9 and VOY. Even with non-traditional main protagonist, that being an African-American Man, and a Female Captain.
However, it seems that we deevolved to the mainly caucasian presence in this show, with 2 minorities, and an alien. A far smaller percentage of the main support characters from as far as I can tell.
Not, to white bash or anything . . . but I was reflecting on a course I took a couple years ago in college, and it got me thinking, after taking a glimpse at ENT.
I mean, it's not suprising, especially seeing that more the 90% of main characters are of Western European decent, or atleast their characters are, on American Television. Not to say that there is anything wrong with that, but at the same time it irks me some.
For instance . . . why is that Rico in Starship Troopers (OK . . . I know this part is off topic, and not even Star Trek) was not casted as Filipino as he is in the novel? (And by the way, I am an American of Filipino decent ;-) )
What would have been great was to see Sulu get his due . . . or another non-standard main protagonist take the lead, in a positive, intellegent, and entertaining role.
