Theoretical contributions of liberal and radical feminism

Radical feminism provides an essential foundation for other feminist schools of thought. It is perceived to be one undesirable element of feminism and the breeding ground for many of the ideas that emanate from feminism. These ideas get pounded or shaped in various ways by the other branches of feminism. Radical feminism was the cutting edge of feminist theory from 1967 to 1975. Kate Millet is considered to be the mother of radical feminism.
