Quote from : It's My Life Now: Starting Over After an Abusive Relationship or Domestic Violence Book

Are boys encouraged to express sadness, fear, or anxiety? In general, our society gives boys permission for one emotion: anger. If a boy is hurt or upset, he may be comforted briefly, but then he is told to stop crying and "be a man." This message usually implies he should hide his feelings. Boys and men are supposed to be solid unemotional rocks. Demonstrations of emotions are seen as "silly." Anger is seen as a sign of strength. Males are considered to be standing up for their rights if they react to a frustrating or undesirable event with anger. Outrage is often the only reaction to an injustice that is allowed from boys.
