There must be 50 ways: Participating in democracy #36: Offer nonviolent resistance to injustice

When brave African American families in places with segregated schools brought their little children to the closest public school they risked consequences ranging from physical threat to arrest. NAACP lawyers fought for their rights over several decades, family-to-family, district-to-district. Eventually the Supreme Court ruled in Brown v Board of Education in 1954 that segregated schools were illegal. 

When African American schoolchildren demonstrated for equal rights in Birmingham and they were arrested in the 1963 Children's Crusade their nonviolent resistance was crucial in convincing Congress and the President to pass the 1964 Civil Rights Act.

When African Americans went to courthouses in counties where they were frequently prevented from voting and they continued to do so even if they were arrested or physically harassed, they were key in causing the 1965 Voting Rights Act. 

Clearly, nonviolent resistance to injustice is a way to participate in democracy, that is, employing the "outside game" to drive the inside game.
