Frances Kissling wants to change the topic

At Feministe, former head of Catholic for a Free Choice Frances Kissling has a post dealing with Missouri's updated informed consent law which includes the following information in information given to women considering an abortion:

"The life of each human being begins at conception. Abortion will terminate the life of a separate, unique, living human being.”

Kissling objects to this information because,

In that brief phrase the most common misunderstanding about abortion is presented as fact. Of course, they meant to say the “Catholic” position and even that is wrong. The best kept secret about Catholicism and abortion is that the Catholic view of when the fetus becomes a person is precisely the same as that asserted in Roe v. Wade. Whatever definition one wants to posit about fetal personhood, the fact is nobody knows.

Wait. What? I didn't see any information about "personhood." I saw a phrase about when life begins and what abortion does to living human beings but I didn't see anything about "personhood." Did you?

Why is Kissling so obviously attempting to change the subject? Does she not have any evidence that the unborn aren't human beings? Can she not muster any defense for the position that the unborn aren't living humans and abortion doesn't kill human beings?
