I don't view those things as exclusive, and I also don't think everyone who goes to these does so for the same reasons. There are different objectives to each kind of political action, but for rallies, the main goal is connecting people with others in their communities who want to do political actions. So, people who do come wanting to effect political change meet others trying to do the same and learn more ways to do it. To be clear, we aren't exclusionary, liberal organizations are present too. People meet groups who want to protest, groups who want to write letters, groups who go to legislative sessions, and groups who give them alternatives to liberalism. Most socialists or other leftists were once liberals, and for those people who are disappointed in Democrats I think it's fair to present them with other options.

For the exclusive goal of showing up in numbers to show frustration at the current political climate, this is accomplished simply by being present and visible, basically. What to do with all the people who are present and visible is the next question. Sometimes it's yelling at passing cars, and sometimes its meeting local orgs trying to drive political change in other ways
