Abortion for boutique eugenics/response

Response points

 * Any tool can be misused: just because a tool can be used for bad things does not mean that it should be outlawed for all uses.
 * Where is the harm in this, as long as it is the parents making this decision?
 * Just because someone with a screenable condition could live a happy/healthy life doesn't say anything about the likelihood that they will.
 * There is no way to ask the fetuses involved what their preference might be, so we have to make the best judgment we can. We don't know that they would always "choose life", given sentience and a full understanding of their situation.
