Hopefully, you understand that much less than 51 percent of the human poplulation can get pregnant.
But no. What I'm saying is that people should not be allowed to kill innocent people with premeditation.
Do you believe a fetus is a separate life? Another human being? I assume you don't. How would you feel about abortion if you did? Do you understand the pro-life arguments about the personhood of an unborn baby? Why do you reject them?
Further, nobody really has full "legal control" over their own bodies. You can't sell your organs. You can't sell yourself for sex. You can't take drugs. Young men can constitutionally be subjected to the draft and placed in combat against their will. So that claim that someone if violating some moral principle if one advocates legislation that would restrict what one can do with one's body is pretty much a non-issue.
My take is that republicans have been winning lately despite that issue and not because of it.
The polling data I recall show that far, far more people vote pro-life as a single issue than pro-choice, and that the majority of voters don't have real strong views on the subject and where they say they stand on it depends on how the question is framed.
What you're really saying is that there should be such a thing as one person having a legal right to the use of another person's body. The basic English word for that is 'slavery', a concept which was abolished somewhere back around 1865 if memory serves. Like I say, I don't see that as a winning issue in America. Republicans have been winning despite that issue and not because of it.
