Pro-choice during the first two trimesters, pro-life except for risk to the mother's life in the third trimester.
That's pro-choice.
It's just like someone saying they are "mostly pro-life" when they want a comprehensive abortion ban with a "maternal life" exception (see Treyvon Martin, apparently).
Anything more pro-choice than that is really just pro-death or a baby hater, the same way anyone more "pro-life" than that is just pro-death or a woman hater.
You would be surprised at how many people here fall under your definition of "pro-death or a baby hater"...
