What is the author's tone in Gender Trouble: Feminism and the Subversion of Identity by Judith Butler?

The tone of Gender Trouble: Feminism and the Subversion of Identity is strongly ideological, densely academic, sexually radical and highly anti-metaphysical. The tone is ideological because it has explicit normative commitments characteristic of a late-20th century feminist intellectual. Butler is hostile to traditional moral views about sex and gender because she sees them as essentialist - they trap inherently fluid individuals into conceptual prisons that force these individuals to serve the interests of cultural, biological, sexual, social and economic elites.
