I forgot to respond to this bit.<quoted text>
Evolution thrives on mutation. Some mutations enable survival of the fittest, others are defective barren mutation mistakes.
So now you're learning something, almost anyway. Mutations cover a broad spectrum. Some don't even make it out of the womb. Others are the fittest at one point in history and not fit at other points in history. Then there are the ones covering a broad spectrum of weaknesses and strengths. It all depends upon what is going on in this big petri dish we call a planet at the time they emerge. I gave an example by mentioning sickle cell anemia. Horrible disease if you've known someone who suffered through it. OTOH, it enhances survival in malaria ridden locations with fairly short life spans by today's standards. Hence the prevalence of the disorder in some family lines. Would you be insulting them due to their "defective" nature.
Barren doesn't mean incapable of contributing to society as a whole. Which is something you keep bringing up.
Society is quite complex and reproductive status isn't central to the contributions of every individual. If we were living in a very primitive society it might be a key issue for survival of a family or a village but we live in a much more complex era. A barren womb with a fertile mind might enhance the survival of large numbers of people whereas a fertile womb only contributes a few individuals.
