Hey there!
Here are the matches:
<em>Young Americans for Freedom: </em>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.
<em>Students for a Democratic Society:</em> 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.
<em>Free Speech Movement:</em> 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!
