So, let's start out with
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.
It doesn't state that all US Citizens are created equal - it states that all men are created equal.
So, our Declaration of Independence is absurdly unrealistic?
I figured you would go here first.
First, that argument spelled out in the constitution is only concerned with the aspect of rights, not general worth. It is making the argument to justify the exception to the general rule that people are unequal by pointing out that they have certian equal rights.
Second, if you go on in the argument, it states that Governments are constructed to secure those rights. Governments can only secure the rights of those that they govern; their citizens. Governments cannot secure the rights of people governed by other Governments. You assertion that, "[our nation has tried] to uphold those same rights the world over. That a man in Afghanistan has those same unalienable Rights" is absurdly irrational and unrealistic. Can you give specifics where our nation has attempted to uphold those specific rights? Or are you just making baseless assertions again? Also, it is not the purview of our government (or do we have it in our means) to secure the rights of People in Afghanistan.
Third, the idea of Natural Rights, as spelled out in the Declaration Of Independence claims that all men are created equal. that does not lead to equal worth. If I go out and kill a family of 4, I have less worth then, say, Mother Theresa. The point is, people may start out being created equal, but that doesn't mean that they have equality of worth as they live their lives. Their actions, the consequences of those actions, their intentions in those taking those actions, their character, habits, etc. all serve to change their worth.
In short, the idea of equal rights due to creation in God's image as spelled out in the Declaration doesn't negate the claim that, in general, humans don't have equal worth. The DOI is spelling out a specific exception to that rule that has realistic limits that are recognized in the DOI. It is also talking about the state of people only when they are created, not throughout their lives, when the actions and circumstances of their lives effect their worth.
Not surprisingly, instead of providing a rational argument to back up your claim, you are trying to discredit mine. In order to do that, you generalizing my argument where I am being specific and mischaracterizing my argument to set up a straw man. So, what you have countered is not my argument. If you truely don't understand it, then ask questions and make an attempt to understand it.
That fact that you, instead, jump right into trying to discredit it indicates that you either assume that you already understand it or are not interested in understanding it. The fact that you are mischarcterizing my argument indicates that you either unknowingly don't understand it, or are intentionally trying to set up a straw man. So, which is it? Are simply being rude and don't care to understand the argument; only wanting to discredit it? Or are you just so ignorant that you don't realize you don't understand it?
Spock willing gave his life - he believed in the needs of the many outweighed his needs.
The willingness of the individual is not relevant to the logic spelled out; the needs of the many outweigh the needs of the few, or the one. Weather or not the "one" is willing doesn't have any effect on the logic in the argument.
