His distaste might come from his parents as well as he feels a diconectedness from them. He seems to be upset with 99% of the world for being phonies because they are not as open as he is. I believe that he was not close to his parents resulting in a distasteful feeling of everyone who is not entirely open and attached to him.
Another sign of the hunting symbols is Holden's wondering of where do ducks go in the the winter. He seems fairly sure that they do not get frozen into the pond, even though he has a need to ask everyone. But if they do not get frozen, where do they go? Does anyone know? It seems peculiar that he was never taught that ducks fly south in the winter. Though, maybe if this block out of memories of his parents is true, his father may have told him, and Holden is holding that information back from himself.
