I was having an interesting discussion with another forum member, and I thought that I would spin off this new thread so we could explore a side issue that came up. Hopefully it will yield some fruitful dialogue.
Let's take a hypothetical scenario: Joe runs a stand where he sells hamburgers and fries those of his neighbors who have a taste for such things. I am not a customer of Joe's, but I am concerned for the health of his customers, I think that Joe should post a sign that shows the nutritional information of his burgers. Let's say I suggest this to Joe, but he's not particularly interested. What sort of authority do I have to force Joe to do what I want? Would it be moral for me to try to do so?
