how does anger cause a problem for romeo and juliet in act 3 scene 5

Lord Capulet grows furious at Juliet's refusal to marry. He calls her "young baggage," and demands she prepare for marriage on the upcoming Thursday (3.5.160). This type of conflict appears several times in Act 3. Romeo speaks of Friar Laurence’s ignorance of his love for Juliet, saying that the Friar could never understand because he is not “young.” Furthermore, the final scene reveals how adults can no longer understand youthful passion. Lady Capulet refuses to consider Juliet’s refusal to marry Paris, and even the Nurse speaks of Paris as a virtuous man worthy of her hand (thus revealing her underlying resentment of her young charge). In response to the Nurse’s patronizing description of Paris, Juliet shouts, "Ancient damnation!" (3.5.235). This serves as both reference to the Nurse's age and to the problems she must deal with, all of which have been created by a feud that has its roots in the older generation. Romeo and Juliet are two young people, who have fallen inescapably in love - only to butt up against the political machinations of their elders - a quandary that has resonated emotionally with teenagers for generations.
