You're kidding, right?!
While very few people on this forum support abortion on demand up to the 40th week of pregnancy (which would be the "100% pro-choice" view) most here would not forbid rape victims from taking a "morning after" pill (which would be the "100% pro-life" view). While viewpoints here would tend to be closer to those of the pro-life side than those of the general public, I would be very surprised if the majority of people here are "100%" pro-life.
On the other hand, given that the legal status quo is about 95% of the way toward the "pro-choice" side (there are a few restrictive laws like parental notification in some states, but the status quo is essentially abortion-on-demand), I think there would probably be a 90%+ consensus that things should move in a pro-life direction even if not everyone agrees exactly how far.
