Another way to look at abortion is with a parallel to slavery, but not from the POV of the slave, but from the POV of the slave owner. The USA became divided in the 1860's and the Civil War was fought because of this slave owner POV that lingered in spite of a widening push for slave rights.
The slave owner saw their slaves as private property and not as a human beings. To them the slave was no different than a horse or a plow, which they legally bought at the store and thereby owned by legal means.
Because of their ownership of private property they felt had the right do as they pleased with the slaves, up and including the death penalty. They had an entitlement mentality that could not see slaves as part of humanity. This did change, after the war was lost. The Southern Democrats who lost the war vowed to rise again, but did so in a different guise of slave owner.
