Easy on the the judgmental lashing, candoxx. Even if you're right, though, it seems pretty plausible that people may have a standing desire to avoid having to handle a sick or special needs child, and that the new, wider availability of tests are simply giving them the information to act on that desire. Therefore, the DIFFERENCE between the abortion rate now and the abortion rate then is the prevalence of the testing, even if it wouldn't have made a difference without the parents' desire to avoid sick children.
