Change the story: bocott evil!
It hardly needs asking, really: stop the flow of money and we choke the source! Boycotts have worked in the past, and Sanctions are nothing more than Big Bad Global Boycotts with clout.

Let Companies know why they are being boycotted, and tell them what they can do to end the boycott.
