…someone who thinks they are sophisticated might be saying something like… “But we have a social contract!”
First, define a social contract. Second, who has a social contract? Third, who decided that everyone was bound to the same social contract? I have no obligation to another individual that I never agreed to be obliged to. On the same token, that individual has no obligation to me since they never agreed to be obliged. You see…being forcibly obliged to other individual(s) is called slavery. Slavery was outlawed in the United States almost 200 years ago.
