I defined rights for my purposes as privileges which it is socially beneficial to extend to all persons. So claiming that it's socially beneficial to allow people to violate your rights can only be true if they weren't rights in the first place, as I defined rights.
You're weaseling. Obviously if you apply a generality such as a right, beneficial to be applied across the board to all people, it will in specific circumstances
not be directly socially beneficial to apply it. That would be the very point of declaring it extended to all persons, and the point of the example I gave, which was not disputed. If the purpose was to maximize social utility, and applying that standard would always maximize social utility in
each specific case there would be no need for the argument that social utility is maximized if the laws were applied
across the board. Otherwise one could simply look at the specific situation and determine that the social utility was maximized in that one specific case.
Examples are copious. A smart Engineer murders her husband. She has no intent of murdering again, and has invented several important innovations, with more in development. If one were to examine how that individual case maximized social utility, one would conclude that there was no value in removing the woman from society.
You start building the arch from the top stone downwards. Social utility must be an aggregate of individual utility. To start at social utility and attempt to reach maximum aggregate individual utility is a pointless exercise. You must assume so much that one would not know where to start. It would boil down to a simple statement - one believes that such a thing must be socially beneficial because one knows socially beneficial things benefit society.
To reach maximum social utility, it only makes sense to begin with maximizing individual utility. Thus, social utility is at best a subordinate function of individual utility.
What you are attempting to do is take a class of children and determine how best to raise the math score by examining their average score, with no reference to the score of the individual child. No matter how much one looks at the composite test scores, one reveals very little.
What you have done is taken this class full of students, and stated that their individual ability, strengths, and weaknesses in math are relevant only in the context of average class test score, and that to maximize average class test score, one should at best briefly take into account individual child test scores.
Utility is just utility. Nobody's utility is more important or more fundamental than anyone else's.
This merely states that individual utility exists. There is no use to this in a discussion about social utility versus individual utility.
I think when your position has been shown to be completely incorrect then you should fix your position first and see how your interlocutor responds, rather than pretending that your position is not incorrect and putting the person who corrected you on ignore.
Anyone who could show my position to be completely incorrect could correctly quote my position. To lie and misquote me is to show me that one is uninterested in discussion, merely grandstanding and lies.
If you believe otherwise, if you believe that there can be non-fallacious arguments that can only be made by changing a person's words, lying about what they said, you are wrong.
