Williamson said she developed her liberal views from her father, Sam, who she called "an armchair revolutionary." When Williamson was 13, she told her father that a teacher told her that the U.S. had to fight the Vietnam War in Vietnam to prevent it from coming to the U.S. In response, her father took her entire family to Vietnam "to make sure the military-industrial complex didn't eat her brain and convince her that war was O.K." Williamson said she was also affected by a trip she took with her family to Soviet-controlled Hungary as a child, and witnessing her father surreptitiously slip their tour guide his business card and tell him: "You get out of here. I'll take care of you the rest of the way."
