These changes can protect transgender people from discrimination. For example, transgender people often have a hard time traveling because they may look like one sex but have another on their papers. These changes can also be needed for transgender people to be allowed to marry their spouses in places where it is illegal for people of the same sex to marry. These changes can even protect transgender people from a wide variety of violence. Some transgender people are only recognized when their documents reveal them. Being revealed as transgender can put people in danger because of transphobia (fear and/or hatred of transgender people).
