Final answer:
The SDS's Port Huron Statement, authored by Tom Hayden, calls for democracy, civil disobedience, and an active role in governance to address economic inequality and discrimination. The YAF's Sharon Statement emphasizes free enterprise, limited government, and anti-communism from a conservative standpoint.
Step-by-step explanation:
The significance of youth in initiating social change was a pivotal aspect highlighted by both the left-wing Students for a Democratic Society (SDS) and the conservative Young Americans for Freedom (YAF). Regarding the assertions that belong to SDS's Port Huron Statement and YAF's Sharon Statement, it is important to differentiate their core philosophies. The SDS's Port Huron Statement, penned by Tom Hayden, called for increased participation in the democratic process, civil disobedience, and the fight against economic inequality and discrimination. It rejected the prevalent anti-Communist position and encouraged ordinary people to take a more active role in governance. In contrast, the Sharon Statement of the YAF embraced a conservative viewpoint, underscoring the importance of free enterprise, limited government, and strong national defense against Communism.
