Santorum is dead on accurate about this.
There are literally thousands of prenatal and congenital diseases that are tested for.
Only a handful actually have any treatments.
So, if we can't treat these diseases, why are we doing prenatal testing?
Well, as the Wikipedia article on prenatal testing points out: "The option to continue or abort a pregnancy is the primary choice after most prenatal testing. Rarely, fetal intervention corrective procedures are possible."
Which is exactly what Santorum said.
So, the question is this: is most prenatal testing really just a cover for doing eugenics?
The answer, of course, is "yes".
Now, that raises a separate set of questions:
For one, if we are doing eugenics on the young, then what happens when, as Mark Steyn points out,
"Timmy Geithner referred only to "demographic challenges" – an oblique allusion to the fact that the U.S. economy is about to be terminally clobbered by $100 trillion of entitlement obligations it can never meet. And, as Chart 5-1 on page 58 of the official Obama budget "Analytical Perspectives" makes plain, your feckless, decadent rulers have no plans to do anything about it."That is, how far off can eugenics on the Baby Boomers be?
Which itself raises another question:
If we are upset about insurance companies doing chromosomal analysis on us and charging premiums based on those analyses, why do we let people do chromosomal analysis on our children and choose to allow them to live or die based on those analyses?
Are we not hypocrites, when we do to our own children what we would never allow government to do to us?
And, how long can we expect government - which is composed by us - to refrain from doing to us what we already do to ourselves?
