First things First

I wanted to explore the Declaration Principles a little more, because there are a few difficult issues that create conflict within the Principles. "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 an issue like slavery, it would seem that the right to Liberty of the slave is at odds with the right of the slave owners "pursuit of Happiness" (property rights). Since we know that slavery is wrong - period, what principle allows us to justify disenfranchising the slave owner of his "property"? Two unalienable rights in conflict with each other, how do we resolve this?
The key to this, and so many other policy dilemmas, is remembering one simple thing: Life, Liberty, and the pursuit of happiness are in a practical order. Without life, liberty and owning property are not possible at all. Without liberty, (as in the example of the slave) owning property is impossible. The order of these rights are in the order of necessary importance, therefore situations where life is an issue will trump any other concern of property or anything else.......etc.
If we apply this to Abortion it becomes clear what the right thing is to do. In the pro-choice argument, they often argue that the baby is her property "get your laws off my body" or that it's an invasion of her privacy (Liberty). But Life should always trump them all.
