You address some excellent issues and I support your position very much. It appears that "normal" healthy people seem to always have the answer to life and death when it comes to those who are not beneficial to their society or meet their standards.
Being a proud father of a gorgeous boy with Down Syndrome I can attest that there have been many in the past who made their positions known while referencing my son's condition. The opinions stated by the elite on here and other places are nothing new to me. They have ranged from nasty descriptions, to an argument about money, to a final assault on my wife and I on why we didn't simply abort "Someone who wouldn't ever contribute" anything. Even our dentist didn't want to talk about braces for our son because "he doesn't really need straight teeth anyway".
The poster you responded to lives in an artificial elite bubble with simple yes and no answers to the most complicated process, life it self. Everyday is a struggle to make sure he gets the SAME treatment as other children, but he will always need more attention. Simply measuring someone's IQ is not the only standard, and having witnessed some of the most glorious eye opening experiences with my son and what he has taught me and other children and adults about what life is really about I consider myself truly blessed.
