People are actually arguing about the value of social justice and are apparently morally apoplectic about preventing a hypothetical resident of a hypothetical island from starving to death.
So my thoughts: I just don't get libertarians sometimes. I would have thought these would be two very easy things to talk about. Apparently it makes a whole swath of libertarians suspect. I hope my brief perusal of the discussion has just given me a misleading picture, but I don't think it has.
