All that the polls show is that a majority now label themselves as pro-life, not that people's views on abortion have changed.
For instance, the majority of Americans have almost always taken the position that abortions should be illegal except in cases of incest, rape, and when the mother's life is threatend, which is primarily a pro-life stance.
About the only things that have switched are the number of people who want to illegalize ALL abortions and legalize all abortions. Where the number of illegalize all has increased while legalize all has decreased.
Besides, it only makes sense consider the younger generations have become even more "pro-life" than that of their parents and grandparents, with young women making up most of the pro-life youth.
In any event, our current laws and what we know of biology only dictates that the logical position would be pro-life.
Otherwise, we shouldn't grant inheritance rights to the unborn.
We should hold physicians liable for harming the fetus.
We shouldn't be throwing doctors in jail for killing the newborn fetus after a botched abortion.
We shouldn't be giving a fetus any legal rights under the law.
Biologically, a fetus is alive since any standard definition of a cell is considered the lowest form of what we consider to be alive.
And therefore it only makes sense to refer to a fetus as human since we consistantly label the dead and rotting as such. It only seems inconsistant to call a rotting corpse human and yet not call the fetus human when the fetus is more living and alive than the corpse.
So we can conclusively establish that the fetus (during any point) is an alive human with legal recognition and status under the law.
Then there's the whole privacy/consent defense which is nothing more than a last resort.
How can one claim that the fetus wasn't given consent to "invade" the mother when the fetus was forcible put there against its will through the sexual conduct of the parents?
After all, if a cop shows up at your door without a warrant, and you grab him by the collar and throw the cop inside your house and the cop finds something you didn't want him to find, would a judge honestly take your defense seriously if your defense was: "I didn't technically give him consent"?
You would be laughed out of the court room. The only reason why this doesn't happen to women is soley because of guilt, not logic.
