Conversely, there is only one human responsibility. To suffer the consequences for whatever you do. This sums it up. You fuck with the bull, you get the horn. Government should intervene in only those events where nearly everyone agrees that it is the right thing to do.
Libertarians advocate a new notion of democratic decision making, the idea of the super majority.
This is no way to run a country for, while it allows you to make a lot of rules, it makes it nearly impossible to enforce them. Think of all the contentious rules we would not have if we required a super majority to pass them. Surely, we would still have laws against murder, rape, armed robbery and the like. I would like to suggest a number for this super majority. In the case of abortion, this would result in no laws being passed at all about it.
