If however, there were a group of people that didn't want to breed with other peoples, they would still be allowed to do that, but the consequences would be on them.
Besides, aren't different traits better suited to different settings? Such as melanin, which is the pigment in human skin, which provides resistance to certain frequencies of light (I'd say UV, but I'm sure Napalmbrain will correct me), favourable in sunnier countries. On the other hand, having a lower metabolism is better in colder countries (for which fat insulates the body). So how would one really breed the 'superior' human for everywhere?
Fair enough.
