You said "It's one thing to protest against genetic manipulation by drawing an analogy with pets in the real world" and in the beginning you said it ethically immoral or at least could be argued as such. I'm saying we manipulate the genes of animals all the time especially when dealing with pets. Perhaps not always in a lab but breeding animals for specific traits has been around for thousands of years.
"And No. Genetically manipulating human genes is unacceptable."
Says you. Have you played Bioshock? I guarantee if gene modification becomes a thing normal people can do and afford we will have people flocking to it like birds, myself included.
We also have people against installing robotic arms or eyes on people but that's already being worked on. A few people calling it unacceptable won't stump scientific advancement (or at least I hope it won't).
We will also have people saying it's unethical NOT to give people gene modification to do stuff like treat genetic diseases. And while you're at it might as well make the baby smarter and stronger and have good teeth, good eyesight and whatever else you can afford. Keep in mind I am fully aware this is a long way away and that we can't do this yet, but I am talking in terms of whenever we can do this reliably.
As for the game and IV changing post encounter/hatching Ame said it's not planned so that's good enough for me. I'm more than happy with the 31 IV mons I have now and if I want more I'll breed them the old fashioned way. What I really need is a knock off TM or a move tutor or something for my Sneasel/soon to be Weavile. (And yes I bred icicle crash onto it)
