From Lydia Sicher: An Unsung Adlerian at http://ourworld.compuserve.com/homepages/hstein/sicherar.htm :
(Masculine Protest)
Sicher presents a strong argument with vivid examples that both men and women protest that men have more value. Although this does not contradict what Adler stated, his examples are those of women resenting their inferior positions and striving to overcome. In popular literature the notion that men attempt to protect their superior positions is not understood. The term "masculine protest," if used at all, frequently is thought of as similar to Freud's notion of penis envy, which only women have. She relates the difficulties that men and women have in cooperating and communicating with each other. Both sexes may see themselves moving on a vertical plane rather than on a horizontal one, thus, they compete and strive to overcome each other.
