The microscopic, mindless entity is as much a human life as a fully-developed brain-dead individual whose life support can be removed, as much as is any living skin cell.
Before it has reached the stage of gestation when it becomes a viable human being, respect the rights of the woman whose womb you wish to consign to the control of the State and your politicians.
