Iran has persisted in avoiding accountability for its nuclear program. It regularly applied misogynistic, ultra-fundamentalist ideals on its people who once had much more freedom to engage in modern society.
One way to engage Iran without leaving the comfort of your home would be a Facebook expression of support for those desiring to change the government. I would encourage people to provide emotional support and encouragement to those aiming to subvert the current political status. It could be as simple as just writing a statement like, "Khameini has got to go!" Send Iran the message that the rest of the world does not like their government.
