Rights do not exist. Individual agreements do.
Here is a proof:
I respect any belief of rights. Your belief may be different from mine. If you peacefully respect my disagreement the same way I respect yours, then "rights" are meaningless in resolving conflicts. If we have the same idea of rights, they are irrelevant. If you force me to accept your vision of rights, you only prove that rights do not help: you abandon reason and take out the gun. There are no rights, only peace or violence. QED.
