There is always a new frontier.
For sex, I mean.
Look at it this way: two centuries ago, interracial sex got people killed. Then it was same-sex sex, and then, after we entered the Light Cone, it was  sex with aliens. And we've never looked back.
Do I think my job is the central to Earth's diplomatic success? No. I'm not that arrogant. But I do think that without people like me, we'd be dead in the water, or maybe just dead.
You see, people don't respect you unless they think you're a person, too. And they won't think you're a person unless you can have sex with them. That's basic instinct to anything with genetic material it wants to pass to the next generation.
So when rational argument fails, and the linguists can't get a grip on the syntax, and a coronal flare impeller is aimed at the sun, it's time for us to go to work.
We're the Kinks.

This earth-shattering idea came out of a conversation I had with my wife last night. We're watching Farscape, and she said, "these things need to have sex with each other."
So what do you think? Should I make some more episodes?
