He was a member of the New York City Board of Education and worked to open the Normal School for Females in 1870.Thomas Kane was supportive in promoting her education, often arguing that these pursuits were more important than her responsibilities at home. Developing her writing skills, she wrote a "Theory" on women in her personal diary. In her "Theory", she saw polygamy as a sexual double standard that held women to a higher level of chastity than men. In general, she criticized the sexualization of women in society. Drawing on her medical background, she claimed that sex leads to pregnancy, which leads to many health complications and often death for a woman after repeated childbirths and pregnancies. She argued that it was morally wrong for men to expect an excessive amount of childbearing from their wives, comparing those wives to saintly martyrs. She was a supporter of "voluntary motherhood", but she didn't necessarily agree with the use of contraception. In her opinion, women should have the right to refuse sexual advances from their husbands, in order to control their own bodies and pregnancies. She advocated for more female doctors who would better be able to care for the female body, as well as sex education for young women before marriage. She created specific guidelines by which sexually transmitted infections could be dramatically reduced. This included castrating infected males, and exiling prostitutes, as well as granting divorces for males and females but forbidding remarriage. She believed more emphasis should be put on women's education rather than marriage, and that marriage should be achieved when one is grown and mature. Kane also believed in educating boys and girls together rather than separately and thought both should be allowed to pursue outside occupations. She strongly supported women's suffrage. Throughout her life, Kane's views on Mormons were constantly shifting and at many times ambivalent. In her book "Twelve Mormon Homes Visited in Succession on a Journey through Utah to Arizona", the title on the second page was ""Pandemonium or Arcadia: Which?"" Kane metaphorically compared the Mormon community to Pandemonium, the city of Lucifer, and Arcadia, the rural Greek paradise. She revealed that the Mormon state was neither Pandemonium nor Arcadia but rather a mixture of both. Kane was content with Presbyterianism and disliked several Latter-day Saint doctrines. She was offended by the Mormon claim to religious authority. She objected to polygamy because she believed it subjugated women. Another reason she claimed to have disliked the Mormons was that she felt they drained her husband of his time and resources, and prevented him from being interested in her own religion.
