Final answer:
By 1967, college students were particularly vocal in their opposition to the Vietnam War, often protesting on moral grounds and due to draft concerns, although the majority of Americans still supported the war effort.
Step-by-step explanation:
By 1967, public opposition to the Vietnam War was especially strong among college students. Many of these students opposed the war on moral grounds, viewing it as a civil conflict where the U.S. should not be involved. The increasing draft also spurred student opposition, as they resisted serving in a war they found unjustified. Despite this growing opposition, the majority of Americans still supported the war effort at this time, often viewing protests as unpatriotic. However, the antiwar sentiment was not limited to students; it spanned across a diverse group of people, including union leaders, minority communities, conservative clergy, and even some veterans. Artists like Bob Dylan and Joan Baez used music to voice their opposition, further amplifying the antiwar message.
