So your civil rights movement idea is nonsensical and a result of our human perception of the Menk as exploited.
But all it takes is a birth one single extraordinary Menk who would start seeing things in a different light. By himself, without needing an alien third party to enlighten him. It's far from impossible. And it's not even unlikely. Plus, I don't even think the Valakians would consider this man (or his movement) dangerous. They do not rule with an iron hand. Hell, strictly speaking, they do not even rule. They facilitate.
Also, there's a chance the Valakian society itself would one day evolve far enough to start realizing the Menk potential. Valakians are far from evil. They're just misguided. And not in an evil, violent way.
PHLOX: We'd be interfering with an evolutionary process that has been going on for thousands of years.
The Menk
ARE evolving, despite the Valakians. The notion that they'd need Valakians wiped out to evolve further is imbecilic.
Of course the Valakians rule the Menk...to classify disallowing/preventing education and depriving them of the right to live on Fertile soil as "facilitating" is outrageous.
As far as all it would take is the birth of 1 extraordinary Menk, you could just as easily say all it would take to cure the Valakians would be one extraordinary Valakian. There already are extraordinary Menk, but, they are being kept down and oppressed.
I haven't actually come down on one side or other about what the "Correct or Moral" decision is, my main argument has been that the oppression of the Menk by the Valakians is
just as important as the Genetic defect of the Valakians. In actuality, I'm on the third side, that it wasn't Archer's decision to make. He should indeed have contacted his Superiors and let them make the call.
I don't think there was really a right answer, I just think it's unfair to side with the Valakians whole hog and think nothing of the plight of the Menk
