Explanation:

A stereotype is a widely accepted judgment or bias about a person or group — even though it’s overly simplified and not always accurate. Stereotypes about gender can cause unequal and unfair treatment because of a person’s gender. This is called sexism.

There are four basic kinds of gender stereotypes:

Personality traits — For example, women are often expected to be accommodating and emotional, while men are usually expected to be self-confident and aggressive.

Domestic behaviors — For example, some people expect that women will take care of the children, cook, and clean the home, while men take care of finances, work on the car, and do the home repairs.

Occupations — Some people are quick to assume that teachers and nurses are women, and that pilots, doctors, and engineers are men.

Physical appearance — For example, women are expected to be thin and graceful, while men are expected to be tall and muscular. Men and women are also expected to dress and groom in ways that are stereotypical to their gender (men wearing pants and short hairstyles, women wearing dresses and make-up.

Hyperfemininity is the exaggeration of stereotyped behavior that’s believed to be feminine. Hyperfeminine folks exaggerate the qualities they believe to be feminine. This may include being passive, naive, sexually inexperienced, soft, flirtatious, graceful, nurturing, and accepting.

Hypermasculinity is the exaggeration of stereotyped behavior that’s believed to be masculine. Hypermasculine folks exaggerate the qualities they believe to be masculine. They believe they’re supposed to compete with other men and dominate feminine folks by being aggressive, worldly, sexually experienced, insensitive, physically imposing, ambitious, and demanding.

These exaggerated gender stereotypes can make relationships between people difficult. Hyperfeminine folks are more likely to endure physical and emotional abuse from their partners. Hypermasculine folks are more likely to be physically and emotionally abusive to their partners.

Extreme gender stereotypes are harmful because they don’t allow people to fully express themselves and their emotions.  For example, it’s harmful to masculine folks to feel that they’re not allowed to cry or express sensitive emotions. And it’s harmful to feminine folks to feel that they’re not allowed to be independent, smart or assertive. Breaking down gender stereotypes allows everyone to be their best selves.
