Maginnis began her activism immediately upon her return to the United States. She canvassed in support of abortion reform bills, before becoming dissatisfied with what she felt was the prioritization of medical professionals over women. SHA advocated for "elective abortion", insisting that all women had the right to safe and legal abortion, free of harassment, and that "[the] termination of pregnancy is a decision which the person or family involved should be free to make, as their own religious beliefs, values, emotions, and circumstances may dictate". SHA provided public education on abortion "by sponsoring symposia on abortion procedures for physicians; providing speakers and literature to libraries, medical schools, physicians, family planning agencies, and individuals; and publishing a quarterly newsletter". Sponsored by the
American Humanist Association, in 1968. SHA operated a free Post-Abortion Care Center (PACC). The organization was disbanded in 1975, two years after the decision in
Roe v. Wade legalized abortion nationwide and voided the Humane Abortion Act.
Association to Repeal Abortion Laws (ARAL) While still heading the Society for Humane Abortion, Maginnis set up another organization in 1966, to carry on underground activities. The main mission of ARAL was to connect pregnant women with abortion providers in neighboring countries. Their list of abortion specialists was well-researched, and depended on members' information and the feedback of the women they referred.
"Army of Three" Rowena Gurner, Patricia Maginnis, and Lana Phelan formed the "Army of Three", which worked on behalf of ARAL to connect women to abortion providers. Women wrote letters from across the country soliciting guidance and information. The three women provided kits to women in need that went beyond a list of doctors: They provided these desperate women with "instructions for going through customs, an evaluation form to be returned to Association to Repeal Abortion Laws after completion of the abortion, summaries of laws, and directions for self-induced abortion". In 2006, artist
Andrea Bowers exhibited her video,
Letters to an Army of Three, as part of her solo exhibition
Nothing Is Neutral at
REfDCAT. The hour-long video features actors reading the original letters sent to the Army of Three in the years before abortion was legal. The walls of the gallery space were covered in Bowers' drawings of some of the letters. Bowers collected the letters after visiting Maginnis in her Oakland home and discovering the activist's personal archive. In 2012, Bowers' work associated with the "Army of Three" letters was revisited in
Wall of Letters: Necessary Reminders from the Past for a Future of Choice at the
