Liberal feminism was largely quiet in the United States for four decades after winning the vote. In the 1960s during the civil rights movement, liberal feminists drew parallels between systemic race discrimination and sex discrimination. Groups such as the National Organization for Women, the National Women's Political Caucus, and the Women's Equity Action League were all created at that time to further women's rights. In the U.S., these groups have worked, thus far unsuccessfully, for the ratification of the Equal Rights Amendment or "Constitutional Equity Amendment", in the hopes it will ensure that men and women are treated as equals under the law. Specific issues important to liberal feminists include but are not limited to reproductive rights and abortion access, sexual harassment, voting, education, fair compensation for work, affordable childcare, affordable health care, and bringing to light the frequency of sexual and domestic violence against women.
