To use words as vague as "life" and "human" when asking questions such has "When does life begin?" or "What is human life?" in the debate on rights application is a testament to the fact that the questioner can't put his finger on the germaine qualities that make the issue relevant.
The proof of this, by example, are the facts that a tree is a life, and a human lymphocyte is a human life. If a person had any idea what he was talking about, he could phrase his question with meaningful descriptors.
You are correct, and I offer my apologies where I failed to meet your standards. I will point to the venerable Remedys post of 159 and reference the link which best expresses my position on this matter:
Personhood Begins At Conception -- by Peter Kreeft, Ph.D. , then offer you you my website,
Christian Patriots For Life to back-up my position(s).
