The problem is testing isn't always that accurate. With down syndrome for instance unless you want to get a test that increases the risk of miscarriage you can expect a 75% reliability of the test with 3% false positives. Now as a choice for an expectant parent I don't have a problem with that it's your decision. As a mandated test that will lead to an abortion get the hell out of here! There is two problems I have with this, despite the risk of miscarriage due amniocentesis testing being small it is real. The state has no right telling a woman she must bear that risk. The other problem gnius has already pointed out in this thinking is it's fascist and inhumane. If you currently go to get tested and the result is a positive the decision lies in your hands as to whether you want to carry that baby to full term. It's even your choice whether you have the test. I can imagine if you take the test there is a little stress involved. Now try and empathize with a woman in your system. This test is now one of the most important and stressful tests of her life. If that test comes out positive you are going to turn around to her and say, "I'm sorry but the government has determined that your pregnancy shall be terminated.". Yeah we've taken the decision away from you and your baby will be killed. When you think these ideas through to their conclusion whether it's banning people from breeding or terminating pregnancies you really how brutal they really are.
