Radical Feminism is the belief that women's oppression is caused
by the patriarchy, which is a system of male authority that is
especially manifested in sexuality, personal relationships, and the
family, but that spills over into the rest of the male-dominated
world.
Radical Feminism holds that "the personal is political," and
does not want women to be treated the same as men, but for their
differences to be acknowledged, and at the same time, both equally
valued. Radical feminism calls for revolution instead of reform,
and wants to dismantle repressive institutions, instead of
re-working them in an attempt to fix them.
Radical feminism has been criticized as excluding other
identities, and focusing only on women - asking black women to
value their identity as a woman more than their identity as a
person of color, for instance. Radical feminism also sometimes
falls into transphobia, saying that transgendered women aren't
really women.
