Although he did not attend college, Sheen credited the Marianists at University of Dayton as a major influence on his public activism, as well as Archbishop Desmond Tutu. Sheen is known for his outspoken support of liberal political causes, such as opposition to United States military actions and a hazardous-waste incinerator in East Liverpool, Ohio. Sheen has resisted calls to run for office, saying: "There's no way that I could be the president. You can't have a pacifist in the White House... I'm an actor. This is what I do for a living." Sheen is an honorary trustee of the Dayton International Peace Museum.
