The theory is interesting, and I take no issue with academic discussion, comparing genomes, thought experiments etc. Where it feels to me like a line is being crossed is by trying to do a physical experiment on involuntary subjects and forcing them to "adapt" (try to survive) something they aren't forced into by nature but by man. It seems unnecessary and arrogant and reminds me of a similar discussion on here about forcing predator fish to eat vegan food sources.
