Getting out and organizing strikes/protests and building third-party grassroots political movements are absolutely great suggestions; neither are voting. Both of them require a significant amount of additional effort than voting. In fact, you may even notice that one requires money, and the other often implies a threat of further violence.

A large reason we are in this is because Americans see voting as the be-all end-all to their political participation. It is the absolute weakest tool to actually enact change in the U.S. political system.
