Uh okay. So if not brightness and rationality (which your previous post suggested), then what should rights be based upon?
Is this some type of trick question? This implies that rights have to be earned or deserved. They don't. They exist as a "thing" in their own right.
BTW,I'm tired of playing your obsession. I am sure you have 137 pages of links ready to go at any time,and that this is a well-practiced routine of yours. You think you are clever,and all you are is practiced and dreary. This might be YOUR only reason for living,but it isn't mine. Find somebody else to play with. All you are doing is using the slightest excuse to "give a speech". You bore me. Go away.
