Replying on my own behalf, I'm not the PP you quoted.
I've had at least 5 miscarriages and one borderline stillbirth (21 weeks). I held the final foetus in my hands - she emerged intact, in a public place. I was, naturally, devastated.
I support abortion to term. I am uncomfortable about it emotionally, but logic and principles dictate that I must. What a woman's body does must be in the woman's control - not the State, any church, her partner or her parents. As long as a foetus is being grown by a woman's body, in her body, she must have dominion over it.
It's bizarre to ask women who've suffered failed pregnancies it they find it hard to acknowledge the loss of life. We have acknowledged it, repeatedly. We have acknowledged that our bodies were unable to create new human beings. I was growing new life and then it stopped.
Do you think my unborn children chose suicide? If you saw them as individual lives, you would have to. That's absurd, of course. My body's attempts to create them failed before completion. This happens all the time. Chemical abortion makes the woman's body inhospitable to foetal development, as mine evidently was by nature. There is no real difference between a miscarriage/stillbirth and an abortion; the differences are entirely emotional and moral.
On a personal note, I find the moral-emotional arguments against abortion distasteful. At least a quarter of pregnancies miscarry, it's more likely to be half. These are not deaths equivalent to the deaths of living children; they're sadly failed biological processes. They can be heartbreaking, for sure. But it's a different category of event.
