It can also involve a significant expense, as well as a serious commitment of time and effort. Until you've done it, it's difficult to understand how hard a process like this can be.
Stories have power, too, and the stories of people who have gone through this process help enlighten the public. The New York Times featured a great article on a program for New York trans residents, the Name Change Project of the Transgender Legal Defense and Education Fund.
