Research on women's preponderance among animal rights advocates explains it exclusively as a product of women's socialization, emphasizing a relational orientation of care and nurturing that extends to animals. The authors propose a more structural explanation: Women's experiences with structural oppression make them more disposed to egalitarian ideology, which creates concern for animal rights. Using data from a 1993 national sample, the authors find that an egalitarian gender ideology is a key difference in women's and men's routes to animal rights (...) advocacy: It differentiates those more likely to endorse animal rights among women but not among men. Neither this ideology nor other variables in the analysis, however, account for women's greater overall support of animal rights in the combined sample. Reasons for this latter finding are explored.
