Difference feminism was developed by feminists in the 1980s, in part as a reaction to popular liberal feminism (also known as "equality feminism"), which emphasized the similarities between women and men in order to argue for equal treatment for women. Difference feminism, although it still aimed at equality between men and women, emphasized the differences between men and women and argued that identicality or sameness are not necessary in order for men and women, and masculine and feminine values, to be treated equally.[3] Liberal feminism aimed to make society and law gender-neutral, since it saw recognition of gender difference as a barrier to rights and participation within liberal democracy, while difference feminism held that gender-neutrality harmed women "whether by impelling them to imitate men, by depriving society of their distinctive contributions, or by letting them participate in society only on terms that favor men.
