It seems to be of great concern to most people not to hold stereotypes against men or women, so for instance women don’t want to be called housewives just for being female. In our society it has become commonplace for women to take on leading roles in politics and business, and are now protected under the law to enjoy the same opportunities as men.
Discrimination clearly exists, however, in many areas of society; in the US, for instance, women are still a minority in politics, and it is a widely held belief that women get paid less than men, even for performing the same job.
Thought experiment: One member of a heterosexual couple is a CEO and the other is a carpenter. Which one is likely the male and which is likely the female?
