No, it wouldn't, possibly, though, because you have no personal self interest in the issue as of yet.

But can you be certain that you would feel the same way if you were the person who was pregnant, or had the chance to become pregnant?

Can you be sure how you'd feel if you were the father and your 17 year-old girlfriend was the pregnant one?

I'd think not.

I don't see how anyone can ever be certain about how they'd feel about any situation that they've never been in or have no chance of being in.

I'm against the death penalty, but I might feel differently if one of my loved ones was the murder victim.

And I'm pro-choice, but I might have felt differently if 10 years ago (I'm waaaaay too old now to be having any new babies) it was my girlfriend who was pregnant with my child (although while I might argue, and prefer that she not get an abortion, i would still relinquish the decision to her without too much argument, but quite possibly not without anger or resentment).

Never having been in those situations, I just don't know for sure how I'd feel.
