We, as humans, are turning more and more selfish and greedy by the day. We are no longer satisfied with being able to have healthy children, we want our perfect image of one as well.
Personally, I want my children to be whoever they're going to be. Brown hair/freckles/green eyes/four toes, who cares? That would be my child and I'd love it no matter what.
This is another step backwards. Can you imagine how many blonde hair/blue eyed kids there would be walking around?
