Though some have defined this as an "irrational fear and hatred, in actuality, from the time most of us are young, people and institutions (parents/guardians, peers, teachers, clergy, the media, etc.) have taught us to conform to societal notions of "proper gender behavior, and to hold in contempt those who challenge or transgress these standards.

Fear and discomfort with gender variant or transgendered people.

Transphobia refers to various kinds of aversions towards transsexuality and transsexual or transgendered people, often taking the form of refusal to accept a person's expression of their internal gender identity (See Phobia - terms indicating prejudice or class discrimination). Whether intentional or not, transphobia can have severe consequences for the object of the negative attitude. Many transpeople also experience homophobia from people who incorrectly associate the medically recognised condition of gender identity disorder as a form of homosexuality (see Homosexuality and Transgender).
