First off, the theory that "human life is sacred." What makes human life better than any other forms of life? It all boils down to our sentience. Now, this doesn't mean that a baby is worthless until it becomes able to think, but that until a baby can live on its own, it is, biologically speaking, nothing more than a tumor. This would logically prohibit "partial birth abortions," as by the third trimester the baby is highly likely to be able to live on its own, outside of the mother. Until that point, objectively, it is a parasite. .
Well, the problem with this is pretty simple. To follow this logic to its conclusion, if a person were to become dependant on others, his life has no "sacredness" anymore. What you are argueing in favor of is a utilatarian view of human lives. This leads to a lot of problems.
First,the severely disabled people aren't independant. Most of them require care for their entire lives (either from nurses or an institution). They are usually brain-injured, which would lessen their sentience quite a bit. Wouldn't that make such a person "a parasite" as well? You could say the same about other people at different stages of life. Newborn babies are the same way, and if anything
more dependant than a disabled person. Then there's the elderly, who once again rely on others for practically everything.
So you see, rationally, if the embryo/fetus has no value as a human, neither do the others I mentioned. So to be logically consistant, under this view, you must also allow for the "post-birth abortions" of the groups I mentioned above. That doesn't happen though. We protect the disabled, newborns, and the elderly.
Secondly the embryo is not a tumor or a parasite. A tumor would be a lump of the woman's own tissues growing out of control. The embryo isn't
her tissue at all. From the moment the sperm joins the egg, it is unique. And I can prove this to you without complex science. If the embryo were simply the mother's tissue (as it would be in a tumor), then there would be no human males. In fact every person born would look extremely similar. So I think the tumor analogy is pretty much false.
Now for the parasite issue. Yes, the embryo does live parasitically off of the nutrients in its mothers blood. But other humans (as I showed above) are just as parasitic. The main difference is that in the case of the disabled or the newborns, or the eldarly, they have their needs supplied externaly rather than by attachment to a uterus. In fact, the distinction doesn't seem to come from a developmental stage in current practice. It comes from other things, a big one being the location of the being in question.
It seems pretty irrational to suggest that a fetus at 20 weeks is "not a person", when the same being, if it was born prematurely, would be a "person". If a woman were to kill a premature baby at 20 weeks gestation, she would be charged with murder. If she goes to Planned Parenthood, a fetus
at the exact same age can be legally killed. That would be similar to saying that people who live in New York can be killed at will, while people living in any other area are protected. It isn't rational to base a person's "worth" based on location.

No, the embryo as I pointed out above is biologically distinct from both father and mother. That isn't true of the sperm or the egg. A sperm or egg is a specialized cell that is produced by the human body, similar to a skin cell. The embryo is completely separate. It isn't valueable because it has thought or instinct, it's valueable because it's human.

No, there are are very good reasons to object to stem cell research. embryos are completely distinct being from their mother, and are therefore human. Like millions of other humans, they depend on others for care and protection. The reason that ESC research is acceptable is that embryos have been
defined as nonhumans. They are still humans, and deserve the same protections as any other humans. Unless you are willing to take the position that it is perfectly acceptable to kill human beings for research, it is irrational to say that ESC research is acceptable.
What you are relying on is an external definition of human, which can (and has) be altered to whatever the society decides it should be. This is irrational because it isn't based on anything other than what your society feels is right, not based on a principle that can be applied consistantly. The human that is considered human today may not be considered so tomarrow.
