I'm not saying oppressed people have a responsibility to change things or that being powerful means you have moral weight behind you. I am saying that breaking an unjust law has no moral value. Gandhi, MLK, and the U.S. Founding Fathers have the moral high-ground because they fought for change. The guy buying pot over the internet is only serving himself. Grouping them all together just because they broke [potentially] unmoral laws is dismissing the motives and sacrifices of the former group.
