It's not a child until it's born. It's a mass of cells... then it's a fetus. It could someday become a child... but while still in the other phases and unable to live on its own... not a child.
Blastocyst, teenager, embryo, toddler, fetus, adult, child, old geezer. All are just words we use to describe a human being at various stages of his or her life. None represent a different type of creature but simply denote an age or a range of years.
You did not come from a fetus, you were a fetus, you did not come from a blastocyst, you were a blastocyst. You didn't, and haven't "become" anything that you werern't before, you have simply grown older and as a result have been called different words that represented your age.
Hence the woman has the control over her own body and anything contained therein. Not me... not you... not the government. BIG GOVERNMENT... BIG REGULATION... BIG BROTHER... STEP BACK!
Are you arguing that the woman owns her child and can therefore do with it as she wishes?
