well, to remove myself completely and look at this from the a clinical/historical perspective, i have to wonder if we aren't contributing to the dilution of the gene pool, this catering to the retarded (yes i use it, look up the definition, it fits) and even encouraging their breeding in some cases merely propagates the condition from which they suffer, and possibly even serves to weaken the human race. That being said, how would you prevent it apart from leaving malformed babies on the mountainside to be eaten by wolves as the ancient greeks did.
.......can i borrow that flame proof suit?
lol... Well, I have a solution that would make religious conservatives shit a brick, but it would work.
Free abortions for potential mothers of retarded babies. We have the technology available to determine what kind of deformities and disorders a baby will have. If we determine a fetus will be retarded, we should basically warn the mother, and leave open the option of an abortion.
I'm personally pro-choice in the first place, but I'm pro-abortion when it comes to these kinds of things. To me, it's just a more efficient version of leaving a baby on a mountainside.
