If we can only go so far with choice, the rational limit would be where things go from a woman controlling her body to her controlling someone else's body. That is what abortion is, after all: an intention to kill another who is innocent of their situation. That goes far beyond.

The real problem is that people are not sure that a ZEF (zygote/embryo/fetus) is human life. I assure you that she is. She meets the scientific definition of life. She receives nourishment from outside to grow herself. And she alone grows herself as only she can read her DNA.

It is essential that she alone can read her DNA because that means she is the sole architect for everything she makes herself thereafter. Her mother provides nothing more than nutrients & a safe environment. A ZEF builds herself beyond those basic necessities all life require.
