Hey there!
Here are the matches:
Young Americans for Freedom: Conservative group in favor of the Vietnam War, lower taxes, and strong anti-communists.
This group was founded in 1960. It's an activist group with conservative views, matching the anti-communism, low taxes, and pro-war views.
Students for a Democratic Society: Advocated for "participatory democracy" and community involvement; anti-Vietnam war.
This group was also founded in 1960 but ended in 1974. It was another student activist group, and this one had views farther to the left.
Free Speech Movement: College students asserting their right to be heard and counted.
This was a major student protest in the mid-1960s concerning the rights of college students at the University of California, Berkeley.
Hope this helps!
