Let's use that same logic and apply it to other rights. Let's start with the "right" to quality and affordable health care. Representative Jesse Jackson Jr. thinks the right to health care is so vital that we should add an amendment specifying as much.
Because our current economic crisis is forcing us to think outside the box, one topic worthy of renewed discussion is health care. What if the Constitution said: "All citizens shall enjoy the right to health care of equal high quality and the Congress shall have the power to implement this article by appropriate legislation?"Without quality and affordable health care, eventually someone's life is threatened. So, if the absence of gay's right marry violated the right to pursue liberty, then by that logic the absence of quality and affordable health care violates someone's right to life.
Let's take another right: the right to a living wage. Without a living wage, how can someone possibly pursue happiness? As such, in order to guarantee the right to pursue happiness, the government must make a living wage a right.
By this logic, we can also make education, housing, food, clothing, and all sorts of other essentials a right. Without them, our right to either or all of the right to life, liberty and the pursuit of happiness would be violated. These are the very rights that are guaranteed in all Socialist states. It's the logic that leads people to believe that gay marriage is a right, and if we allow this logic to take hold, soon enough we'll be guaranteeing "rights" the way they do in Socialist nations.
