Ok, this belongs in off tipic, because this is exactly what this is.
I have been watching some Voyager episodes, and one of them had Seven of Nine explaining that a particular race were considered 'undesirable for assimilation'. she stated "why assimilate someone that will make the collective worse?" My question is this.
How BAD does your race have to suck, that the borg would rather assimilate tribbles over you???
I mean what good does a tribble bring to the borg. It's like the borg are resorting to luring people in with a cute cuddly ball of fur that reaches out and infects you.
Perhaps they have some as of yet unheard of desired trait. Maybe the borg were tricked into adding them to the collective? And yes you'd have to be pretty bad to have tribbles picked over you. Takes me back to days of being picked last for dodgeball
