It’s hard to remember exactly, but I think I first noticed it back in the days of Star Trek: Deep Space Nine. It’s even possible it really started in the earlier series, Star Trek: The Next Generation. By the time of the final series, Star Trek: Enterprise, it was definitely a thing, and by then it went way too far.
In the original Star Trek series, Gene Roddenberry gave us Vulcans. They were, in many ways, better than humans. They lived longer, they were stronger and smarter, and — crucially — they were, in some ways, wiser than us. Rick Berman, Roddenberry’s heir apparent, re-wrote that vision to make them conniving, lying, self-interested bastards. In other words, he made them more human.
My question here is: Why did our heroes turn into such assholes?
