Final answer:
Feminist theory suggests that the social construction of sexuality is based on power and not solely on biological gender differences or the media. Power differentials exist in matters of sexuality, and dominant groups actively promote their own worldview and economic interests. The debate over the legalization of gay marriage is an example of the manifestation of power differentials in society.
Step-by-step explanation:
Feminist theory suggests that the social construction of sexuality is based on power. This means that societal definitions of appropriate sexual behavior are shaped by those in power, rather than being determined solely by biological gender differences or the media. Feminists argue that power differentials exist in matters of sexuality and that dominant groups actively work to promote their own worldview and economic interests. For example, the debate over the legalization of gay marriage is seen as a manifestation of power differentials in society.
