in the defense of Smith, Donaldson and the other two lawyers marked a turning point in gay rights on the West Coast of the United States. Decline Following the Jennings trial, the group expanded rapidly, with founders estimating membership in California by May 1953 at over 2,000 with as many as 100 people joining a typical discussion group. Membership diversified, with more women and people from a broader political spectrum becoming involved. With that growth came concern about the radical left slant of the organization. In particular, Hal Call and others out of San Francisco along with Ken Burns from Los Angeles wanted Mattachine to amend its constitution to clarify its opposition to so-called "subversive elements" and to affirm that members were loyal to the United States and its laws (which declared homosexuality illegal). In an effort to preserve their vision of the organization, the Fifth Order members revealed their identities and resigned their leadership positions at Mattachine's May 1953 convention. With the founders gone, Call, Burns and other like-minded individuals stepped into the leadership void, and Mattachine officially adopted non-confrontation as an organizational policy. Some historians argue that these changes reduced the effectiveness of this newly organized Mattachine and led to a precipitous drop in membership and participation. Other historians contend that the Mattachine Society between 1953 and 1966 was enormously effective as it published a magazine, developed relationships with allies in the fight for homosexual equality, and influenced public opinion on the topic too. During the 1960s, the various unaffiliated Mattachine Societies, especially the Mattachine Society in San Francisco and MSNY, were among the foremost gay rights groups in the United States, but beginning in the middle 1960s and, especially, following the Stonewall riots of 1969, they began increasingly to be seen as too traditional, and not willing enough to be confrontational. Like the divide that occurred within the Civil Rights Movement, the late 1960s and the 1970s brought a new generation of activists, many of whom felt that the gay rights movement needed to endorse a larger and more radical agenda to address other forms of oppression, the Vietnam War, and the sexual revolution. Several unaffiliated entities that went under the name Mattachine eventually lost support or fell prey to internal division. In 1973 Hal Call opened the Cinemattachine, a venue showing both Mattachine newsreels and pornographic movies. The Cinemattachine was an extension of the Mattachine Society's
