As in "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."

In this context, a right is an innate attribute of a person. A right serves as a guide for behavior in that it names good, correct and righteous pursuits. Actions, having as a goal sustaining one's life are congruent with this guide. Enacting legislation providing for such behavior as legal is also congruent with this guide.

Suggesting that a only a group of people rather than an individual have the right to life is just plain bizarre.
