Responsibility I believe accrues through privilege. People like you and me have an unbelievable amount of privilege and therefore we have a huge amount of responsibility. We live in free societies where we are not afraid of the police; we have extraordinary wealth available to us by global standards. If you have those things, then you have the kind of responsibility that a person does not have if he or she is slaving seventy hours a week to put food on the table; a responsibility at the very least to inform yourself about power. Beyond that, it is a question of whether you believe in moral certainties or not.
