Transphobia
Transphobia refers to discrimination against trans people. This is expressed, for example, through rejection, anger, intolerance, prejudice, discomfort or physical or psychological violence towards trans people or people who are perceived as trans. Internalized transphobia is hostility that is directed against one's own trans identity and thus against oneself. This often happens in a trans-phobic environment and/or before one's own inner coming out.
