There are of course many logical absurdities in the Star Trek universe. (e.g. Every intelligent species except for humans has always lived under a single culture and language.) and though I'm sure that many others have covered this before I can't help but be intrigued by his carousing. Am I the only one who wonders how it can be that all alien species are divided into "male" and "female" in ways that human beings can easily recognize? What are the odds that a single alien species would evolve something approximating a vagina well enough to accommodate the human penis, let alone all of them? Why does the "Enterprise" never run into intelligent beings who reproduce asexually? Or exchange genetic information in ways wholly different from sex as we know it?
"Star Trek's" paper thin metaphors calling for racial harmony may be admirable, but I'm afraid I simply can't stand behind such egregious anthropocentricism. They have simply paved the way for a "new" order in which, instead of the European man raping the world, mankind comes together in locker-room brotherhood to rape the universe. Tragic folly indeed.
