The anti-war movement affected young adults in American society by mobilizing them to actively protest against the Vietnam War, influencing cultural expression through music, and fostering social and political awareness.
Step-by-step explanation:
The anti-war movement had a significant impact on young adults in American society during the Vietnam War. Many young adults joined the movement and actively protested against the war, expressing their opposition to the US government's involvement in the conflict. They organized demonstrations, participated in sit-ins, and engaged in other forms of civil disobedience to voice their discontent.
