Romney: Contraception is between a man and a woman... it's none of my business.

Here-I'll help you focus and try to formulate a cohesive argument:

I posted some basic biology links you could use to educate yourself. They demonstrate what people who passed biology in high school already know. Life begins at conception. Since that life's genetic material is a combination of two human parents, it is certainly a human life.

Now, you have argued that this human life can not yet claim "personhood." Maybe you can start by demonstrating that there is some basis for this claim. I would expect that you would mobilize some sort of scientific evidence, since you have shown an aversion to cultish or religious-esque explainations.
