I must admit to being a Trekker; although I enjoyed the original series I think I was too young to understand the messages in the show. It wasn’t until The Next Generation that I became aware of just how clever, and progressive, the show was. I certainly recall the episode “The Outcast’ that you refer to, and the dilemas felt by the main characters as ‘impure feelings’ began to surface. There was also the discomfort felt by the aliens because of the open gender displays by the Enterprise crew. Sadly, if I recall, the female alien is forced by her people to undergo ‘corrective’ treatment and is thus ‘cured’ by being forced to conform to society standards.
The show’s creator, Gene Roddenberry, intended each episode to have two levels, the first simply a suspenseful adventure story and the second a morality tale. At a time that western society, particularly that of the US, was grappling with many social issues, Roddenberry portrayed his futuristic humans as having altruistic values that they had to apply to situations that were in fact allegories of contemporary cultural realities. Issues depicted in the various series included the value of personal loyalty, racism, religion, human rights, sexism and feminism.
Even the physical appearance of the various ‘alien’ races was designed to highlight the fact that even though ‘we’ all look different there are common basic similarities. Of course all that didn’t stop me dreaming of looking like Seven of Nine! I think it would be easy to say that one simple message from Star Trek would be “Be who you are and not who others might expect you to be.”
Next time you find yourself watching an episode of Star Trek just consider it social studies.
