You asserted, "... bear in mind that "conception" is not "fertilization"." Uh, you and GS still trying to toss out this BS? Trying to dehumanize the embryos of IVF (yes, IVF conceives embryos in a petri dish, Orrin Hatchling's absurd assertion aside) to make them fair game for exploitation?
Not at all. I think that every fertilized egg is a full-fledged human being and do not believe that the purposeful destruction of IVF embryos should be an option. I fully agree that the purposeful destruction of embryos is infanticide.
But that doesn't change the fact that fertilization is not conception (that is, the baby comes into existence before the mother "catches" it and becomes pregnant). If anything, the birth control movement has been confusing the two to promote procedures and drugs (e.g., the "morning after pill" and even the normal birth control pill) as preventing conception to hide the fact that they destroy fertilized eggs and embryos by preventing them from implanting. It's like tying a woman's hands behind her back so she can't catch a baby that's falling toward her.
It also doesn't change the fact that some percentage of fertilized eggs naturally do not implant, get absorbed by a twin, stop growing, or otherwise don't make it to birth, regardless of what a woman does. I look at the fact that the fertilized eggs that don't make it have no more impact on the humanity of a fertilized egg or embryo than the high infant mortality rate in a famine situation has an impact on the humanity of a born child.
So, please, take your assumptions about my motives elsewhere. I've marched in pro-life marches and have counter-protested pro-choice marches. I've also talked people into changing their mind about abortion and I'm refusing vaccines for my daughter that are made with fetal cell lines (in the process, making various doctors aware of this issue).
No, I'm not trying to defend the purposeful destruction of embryos or embryo experimentation, both of which I oppose. I'm trying to give people a reality check because there is a distinction between "conception" and "fertilization" (they are not the same thing) and the claims being made in this article are not entirely unreasonable, just as couples who try to have children when the woman has a Luteal Phase Defect, for example, can wind up losing a lot of children without IVF or medical intervention (that is, naturally). Lots of fertilized eggs die -- naturally -- because they are genetically defective or for a variety of other reasons. Facing that doesn't change anything about the humanity of fertilized eggs as unborn children.
