A play on words referring to the Jehovah’s Witness
Jehovah’s Witnesses commonly refer to their religion simply as “The Society,” “The Organization,” or “The Org” for short. The online ex-Jehovah’s Witnesses community started drawing comparisons between the religion and the Borg race of Star Trek, and thus the phrase was born.
In the words of John Cedars, a well-known ex-Jehovah’s Witness: “The fictional Borg were half organic and half robotic. Individually, they were all formerly independent people who were at one time captured and 'assimilated' by the Borg, at which point they were robbed of their humanity and everything that made them an individual. Once appropriated into the Borg, one cannot think or act as an individual, but only as part of the collective. It's a worryingly accurate metaphor that plays on the Society's obsession with unity and organization.”
The best decision I ever made was to leave the Borg.
