There are several strands of feminist legal theory, including liberal, radical, cultural, Black, postmodern, and pragmatic feminisms. Radical feminism views patriarchy as the fundamental source of inequality, seeking to transform relationships between the sexes. It argues that pornography perpetuates male dominance and desensitizes men to violence against women. Cultural feminism believes there is a distinct feminine approach to moral issues that differs from the male-centered legal system. Feminist theories have been criticized for potentially essentializing women and ignoring diversity in women's experiences.
