A woman (with the man's input if she chooses) has the right to have or abort any child she chooses. I support a woman's total right to choose. It doesn't matter if the baby has Down Syndrome or if the baby is 100% healthy; if the mother doesn't want it for whatever reason, so be it.
I do think that it's totally fine to have a baby with Down Syndrome. Having interacted with others who have mental, physical, learning, etc. disabilities, I think differently about quality of life. While a person with Down Syndrome may not have the life you would desire, I'm sure that there are plenty of people with Down Syndrome who enjoy the life that they are afforded.
Finally, double check the fact about women releasing trillions of eggs each month. It's not accurate. Unless you were using sarcasm in which case, I missed it.
Thanks for an interesting read and I'm hoping for a great discussion!
