In the book Johnny Tremain, why does Johnny still think of himself as an Englishman?

During the course of the novel, Johnny is in fact still an Englishman. He still feels a kind of loyalty to England and an empathy for Tory supporters. (Example: Chapter 6, the Tory is beaten for chasing the street gang that tacked a plaque on his property). None-the-less, over the course of the novel, Johnny finds himself drawn to the spirit of freedom and supportive of the Sons of Liberty. Johnny is honest and honorable; he joins in the raids, but he does not participate in the violence. As time goes on, Johnny becomes an true American.
