I have to disagree. I more or less understand the pro-life point of view, which is that a fetus is a precious life. Since I'm not religious, it's clear to me that the fetus is alive, but I don't see it's life as important until it is capable of thought, emotion, and sentience, in general. I would say this is the essential difference between most pro-life and pro-choice philosophy.

After that, I switch to a much more consistent version of "pro-life" which includes a moral imperitive not to cause undue (frivolous, even) suffering or harm to any living thing.

It is not just that they see the world differently, their language does not even try to counter the opposing side's argument.
