So I have the right to my own life, and I can do with it (or do away with it) as I see fit, barring my intrustion on anyone else's rights.
Also the Declaration is not a legally binding document and our laws are not shaped by it, but I think it does well to help illuminate the idea that I have a right to my own life, and the government will not dictate whether or not I will excercise that right.
Grow up. "Rights" are also duties, that is they are part of a coin, an inseperable pair.
Your right to life is a duty to uphold that life and protect it.
Your right to liberty is a duty to protect that liberty and use it to good -- to godly -- ends.
Your right to "the pursuit of happiness" means not doping up to the gills or 24/7 porno, but rather the pursuit of that spiritual happiness by the uplifting enjoyment of wordly things applied to divine service. Only you, the individual *can* know to as full a depth as might be acheived for what purpose G-d has set your soul into your body and provided to you every moment of existance. That is the honest root of private property and liberty as a duty.
