Fraternities are made up of insecure men who bond through homophobia and by getting sex. The pledging process reinforces this by teaching men that women are to be devalued. Because of this 70 to 90 percent of all gang rapes on college campuses are perpetuated by fraternity members.
ROTC also reproduces hegemonic masculinity in order to create warriors. This occurs through cadences that talk about degrading women and insulting cadets who are unable to perform with insults that are usually used for women.
Sports teams also reproduce hegemonic masculinities by encouraging men to overcompensate their masculinity due to how close their bodies are to other men on the sports field and in the locker room.
The degree to which hegemonic masculinity is expressed depends on a man's class and his geographical location.
