definitions of our nature." GLF groups rapidly spread throughout the United States and other countries. Members did not limit activism to gay causes. In late 1960s and early 1970s, many homosexuals joined protests with other radical groups such as the Black Panthers, women's liberationists and anti-war activists. Lesbians brought the principles of radical feminism on the emerging new philosophy, and GLF activists argued that the institution of heterosexual families necessitated the oppression of homosexuals, allowing them to define their gayness as a form of political resistance. GLF activist Martha Shelley wrote, "We are women and men who, from the time of our earliest memories, have been in revolt against the sex role structure and nuclear family structure." Though the GLF effectively ceased to exist in 1972, unable to successfully negotiate the differences among its members, its activists remained committed to working on political issues and the issue of homosexuality itself. GLF's legacy informed gay and lesbian activism throughout the late 1980s and early 1990s when groups such as ACT UP and Queer Nation formed to fight AIDS and homophobia. Many of the leaders of these two groups had been either active in or heavily influenced by the ideas first promoted by GLF. Even though many activists became disenchanted with the organization, their determination to carry forth the spirit of gay liberation through new groups such as the Gay Activists Alliance and the Radicalesbians proved invaluable in the continuing fight for GLBTQ rights.

It formed the public part of the early homophile movement, with a public office, administrative infrastructure, logistics, a telephone, and the first publication that reached the general public, ONE Magazine, a huge leap of gay movement. The Los Angeles Postmaster seized and refused to mail copies of ONE Magazine in 1954 on grounds that it was "obscene, lewd, lascivious and filthy." This action led to prolonged court battles which had significant influence on gay and lesbian movements. In 1958, the Supreme Court of the United States ruled unanimously in One, Inc. v. Olesen that the mere discussion of homosexuality was not obscene, and the magazine continued to be published and distributed
