What Dawkins said and how he expressed it was... insensitive. But from a purely evolutionary/biological point of view, arguing that it makes sense to terminate fetuses with developmental disabilities is pragmatic.
From a purely evolutionary standpoint, it's not necessary to abort for Down syndrome. I'll demonstrate why:
Let's have a show of hands of all the people in this thread who have deliberately procreated with someone with Down syndrome.
Anyone?
Anyone?
Gee, why not? What does everyone have against people with Down syndrome? A woman with Down syndrome has a 35%-50% chance of bearing a child with Down syndrome. (Males with Down syndrome are commonly infertile, so we'll just stick with the ladies). Children with Down syndrome are reportedly filled with sweetness and light (don't get me started on that unfair stereotype) and undeniably cute as buttons. What the hell, people? Why haven't you married a woman with Down syndrome and started a wonderful family?
And ladies, you're not innocent either. Why aren't you lining up to have a woman with Down syndrome donate her chromosomaly enhanced eggs to you?
Well, I am sure there are a lot of reasons and none of them are "eugenics." We're not trying to create a master race or anything. Childbearing is a spin at the roulette wheel that occasionally lands on Down syndrome. How an individual handles that depends on what they value and what one wants or hopes for their children and families. For some people, a child with Down syndrome is welcomed as a chance for the family to learn and grow. But as much as people who don't happen to have these kids want to imagine that's the camp they'd choose, reality would beg to differ.
If there is one thing I've learned from running a support group for parents who have ended a pregnancy following a prenatal diagnosis, it's that people who start out swearing they would never abort because of fetal anomaly run at about 80% of the population. Yet depending on what research you're looking at, 80%-90% absolutely do abort when there is a serious diagnosis.
The math adds up to an awful lot of people who right now are dead certain they'd never make that choice, who actually will make that choice after they get a poor prenatal diagnosis. I have seen it so many times in the stories of women coming to my web site that start with "I never thought I'd" "I never imagined" "I skipped the early tests because I thought I'd never."
Obviously, it runs right into a lot of emotional and volatile issues concerning disability rights and the value of disabled people's lives, so I can understand why parents of children with Down's Syndrom and people with other disabilities took it badly.
Absolutely. And Dawkins really doesn't have any business questioning the morality of the small percentage of folks who carry those pregnancies to term. Their babies, their decision, period.
But from the way some people have reported it, you'd think Dawkins said "Kill all disabled people."
I think he was (clumsily) attempting to counterbalance the popular argument that those who abort because of fetal anomaly are automatically immoral, selfish and so on. I've seen that argument a bazillion times and it doesn't hold any water, and the people who unquestioningly accept it as "truth" (without ever giving the parents the benefit of the doubt or taking a nanosecond to consider what the child would go through, and can't shut up about what
they have learned and how
their own lives have been enhanced) are legion.
Abstract intellectual discussions can't coexist with people whose personal feelings govern all discourse.
This is actually an extremely personal topic for me ... I am trying not to let my feelings govern.
