Why does Holden hate “phonies”?

Holden characterizes “phonies” as people who are dishonest or fake about who they really are, or people who play a part just to fit into a society that Holden questions. Therefore, Holden hates “phonies” because they represent everything he fears or fights against, such as adulthood, conformity, and commercialism. He describes this hatred when he says, “You never saw so many phonies in all your life, everybody smoking their ears off and talking about the play so that everybody could hear and know how sharp they were. . . . You should’ve seen the way they said hello. . . . It was nauseating. The funny part was, they probably met each other just once, at some phony party.” Everywhere Holden goes, he distrusts the insincere intentions and phony actions of his peers as they navigate adulthood and try to fit into society’s expectations.
