And then came the 14th Amendment: Incorporation
No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
Ok, I give up: how does the language that you quoted "incorporate" the bill of rights against the states?
Many people who revere the original Constitution are appalled at how the 14th Amendment, as carried to bizarre extremes by the courts, has extinguished state sovereignty.
Relevant to the original point of this thread might be this: Does any citizen has the right to "choose" to deprive another human being of life (and thereby of every other freedom), just because they are unborn?
We now know from ultrasound and other evidence how trivial birth is, compared to other events in life. There must be hundreds of thousands of people walking around who were born prematurely. One might ask why their shrivelled, grotesque little bodies were not thrown out like aborted fetuses? After all, it's not convenient or cheap to keep a severely premature infant alive. Does someone's value or right to live depend entirely on the will of someone more powerful?
We're all likely to be infirm, decrepit, and dependent someday. Would you like your life to depend on whether someone else finds you "convenient" to have around, or would you rather stick with the Judeo-Christian belief that all human life is sacred? This is not a small issue, it is not a "single issue." It goes to the heart of what civilization is.
