The Serlings were active members of the Unitarian Community Church of Santa Monica and Rod was an dedicated supporter of the Unitarian Universalist Association, the Santa Monica church, and the American Civil Liberties Union (ACLU). He supported these organizations and others through speaking engagements and with financial contributions.[2]
In a noteworthy speech delivered at Moorpark College, Moorpark, California, on December 3, 1968, Serling criticized loyalty oaths, the Vietnam War and social inequity.
Serling's political involvement was not limited to his writing, however, and he campaigned for Democratic incumbent Pat Brown against Ronald Reagan in the 1966 California gubernatorial race.
