In 1969 he graduated from Cornell University where he had helped form the Cornell Student Homophile League, which was only the second such homophile group established at an American university.  In 1969 he moved to Canada and worked as a research assistant at the University of Toronto.  Here he founded the University of Toronto Homophile Association (UTHA) which held its first meeting on October 24, 1969.  UTHA was the first gay and lesbian group to be established in Toronto and would eventually grow into the Community Homophile Association of Toronto (CHAT).  Moldenhauer went on to open the Glad Day Bookshop in 1970, which challenged Canadian censorship laws by selling erotic and gay liberation books, such as "The Joy of Gay Sex".  He was also a founding member of the monthly magazine, and one of Canada's first significant gay periodicals, The Body Politic.  He has also been involved in such groups as Toronto Gay Action and the Gay Alliance Toward Equality, and has helped establish the Canadian Gay Liberation Movement Archives, which eventually became the Canadian Lesbian and Gay Archives, one of the largest archives of gay and lesbian documents in the world.  On February 13, 1972 he became the first gay liberation representative to address a political party conference in Canada when he addressed a session of the New Democratic Party Waffle convention.

National Women's Liberation Conference: The National Women's Liberation Conference (or National Women's Liberation Movement Conference) was a United Kingdom initiative organised to bring together activists in the Women's Liberation Movement with an aim to developing a shared political outlook.  Ten UK conferences took place between 1970 and 1978.  There was a Welsh conference in 1974 and a Scottish conference in 1977.  During these conferences the seven demands of the UK Women' Liberation Movement were formulated:

Feminist movement: The feminist movement (also known as the women's liberation movement, the women's movement, or simply feminism) refers to a series of political campaigns for reforms on issues such as reproductive rights, domestic violence, maternity leave, equal pay, women's suffrage, sexual harassment, and sexual violence, all of which fall under the label of feminism and the feminist movement.  The movement's priorities vary among nations and communities, and range from opposition to female genital mutilation in one country, to opposition to the glass ceiling in another.  The bourgeois women's liberation movement and the proletarian women's liberation movement both are feminist terms, and there is no difference between the two.  Simply put, feminism means that women deserve equal rights.

Men's rights movement: The men's rights movement (MRM) is a part of the larger men's movement.  It branched off from the men's liberation movement in the early 1970s.  The men's rights movement is made up of a variety of groups and individuals who focus on numerous social issues (including family law, parenting, reproduction, domestic violence) and government services (including education, compulsory military service, social safety nets, and health policies), which men's rights advocates say discriminate against men.

National Liberation Movement (Ghana): The National Liberation Movement was a Ghanaian political party formed in 1954.  Set up by disaffected Ashanti members of the Convention People's Party, who were joined by Kofi Abrefa Busia, the NLM opposed the process of centralization whilst supporting a continuing role for traditional leaders.  Its main founding member was linguist Baffour Akoto whilst J. B. Danquah served as leader.  The party gained some support in the Gold Coast legislative election, 1956 and became the third largest party in the Assembly with 12 seats, behind the Convention People's Party and the Northern People's Party.

Sudan People's Liberation Movement: The Sudan People's Liberation Movement (SPLM) (Arabic: الحركة الشعبية لتحرير السودان‎ ‎ , "Al-Ḥarakat ash-Shaʿbiyyat liTaḥrīr as-Sūdān") is a political party in South Sudan.  It was initially founded as the political wing of the Sudan People's Liberation Army (SPLA, key protagonist of the Second Sudanese Civil War) in 1983.  On January 9, 2005 the SPLA, SPLM and Government of Sudan signed the Comprehensive Peace Agreement, ending the civil war.  SPLM then obtained representation in the Government of Sudan, and was the main constituent of the Government of the then semi-autonomous Southern Sudan.  When South Sudan became a sovereign state on 9 July 2011, SPLM became the ruling party of the new republic.  SPLM branches in Sudan separated themselves from SPLM, forming the Sudan People's Liberation Movement-North.  Further factionalism appeared as a result of the 2013-2014 South Sudanese Civil War, with President Salva Kiir leading the SPLM-Juba and former Vice President Riek Machar leading the Sudan People's Liberation Movement-in-Opposition.

Movement for National Unity: The Movement for National Unity was a political party in Saint Vincent and the Grenadines.  It was formed shortly before the 1984 general elections by a split from the United People's Movement due to the refusal of most party members to disown Fidel Castro's politics.  Some of the support for the Movement for National Unity was the result of absorbing former members of the disbanded Youlou United Liberation Movement of the 1970s.  The new party received 2.0% of the vote, but failed to win a seat.  In the 1989 elections it increased its share of the vote to 2.4%, but remained seatless.  However, in the 1994 elections it received 17.4% of the vote and won a single seat.  In the same year it merged with the Saint Vincent Labour Party to form the Unity Labour Party.

Justice for Men and Boys: Justice for Men and Boys (and the Women Who Love Them) (J4MB) is a British political party which identifies with the Men's rights movement and opposes feminism.

Men's movement: The men's movement is a social movement consisting of groups and organizations of men and their allies who focus on gender issues and whose activities range from self-help and support to lobbying and activism.  Despite the term "men's movement" implying a single, unified movement, the men's movement is actually several movements that have differing and often antithetical goals.  Major movements within the men's movement include the men's liberation movement, profeminist men's movement, mythopoetic men's movement, men's rights movement, and the Christian men's movement, most notably represented by the Promise Keepers.  The movement exists predominantly in the Western world and emerged in the 1960s and 1970s.
