Feminist movements and ideologies
Radical feminism considers the male-controlled capitalist hierarchy, which it describes as sexist, as the defining feature of women's oppression. Radical feminists believe that women can free themselves only when they have done away with what they consider an inherently oppressive and dominating patriarchal system. Radical feminists feel that there is a male-based authority and power structure and that it is responsible for oppression and inequality, and that, as long as the system and its values are in place, society will not be able to be reformed in any significant way. Some radical feminists see no alternatives other than the total uprooting and reconstruction of society in order to achieve their goals.
Transfeminism
Transfeminist critics of mainstream feminism say that as an institutionalized movement, feminism has lost sight of the basic idea that biology is not destiny. In fact, they argue, many feminists seem perfectly comfortable equating sex and gender and insisting on a given destiny for trans persons based on nothing more than biology. Transfeminism resists and challenges the fixedness of gender that traditional approaches to women's studies depend upon.
