time. James J. Reeb, a minister at All Souls Church, Unitarian, in Washington, D.C. and a member of the Southern Christian Leadership Conference, was clubbed in Selma, Alabama on March 8, 1965, and died two days later of massive head trauma. Two weeks after his death, Viola Liuzzo, a Unitarian Universalist civil rights activist, was murdered by white supremacists after her participation in the protest march from Selma to Montgomery, Alabama. The Selma to Montgomery marches for voting rights are best known for Bloody Sunday, which refers to March 7, 1965, the most violent of the three marches. The past head of the Unitarian Universalist Association 2001–2009, William G. Sinkford, is African-American, making Unitarian Universalism one of the first traditionally white denominations to be headed by a member of a racial minority. While political liberals make up a clear majority of Unitarian Universalists, the movement aspires to diversity, and officially welcomes congregants regardless of their political views. Politically conservative Unitarian Universalists point out that neither theological liberalism nor the Principles and Purposes of the UUA require liberal politics.

Unitarian Universalists have been in the forefront of the work to make same-sex marriages legal in their local states and provinces, as well as on the national level. Gay men, bisexuals, and lesbians are also regularly ordained as ministers, and a number of gay, bisexual, and lesbian ministers have, themselves, now become legally married to their partners. In May 2004, Arlington Street Church, in Boston, Massachusetts, was the site of the first state-sanctioned same-sex marriage in the United States. The official stance of the UUA is for the legalization of same-sex marriage—"Siding with Love". In 2004 UU minister Debra Haffner of The Religious Institute on Sexual Morality, Justice, and Healing published An Open Letter on Religious Leaders on Marriage Equality to affirm same-sex marriage from a multi-faith
