While reading this review( http://www.thehousenextdooronline.com/2009/05/star-trek-90210-or-star-trash-or.html) of "STAR TREK", I came upon this interesting passage that criticized the franchise's portrayal of cultural or ethnic diversity in the fictional 23rd and 24th centuries:

Because despite the assertions of Star Trek’s countless producers and myriad fans, the entire franchise (but mainly the original series) has always been about underlining 20th century prejudices, but on a cosmic scale. The only species not defined by an overarching, stereotypical character trait is the humans. All others can be described with one word, and one word only: Vulcans are soulless, Klingons are aggressive, Ferengi are sly, etc. The arrogance on display is palpable: Only Homo Sapiens have the right answers, the rest of the races littering the galaxy are somewhat primitive, despite their mastery of space and time well in advance of us. The ones that are slightly more well adjusted, like Spock or Worf, have all adapted to our ways: this is not integration, it’s assimilation
