A children's book that implies being gay is a reversible condition caused by childhood sexual abuse has been submitted to the Supreme Court as part of an amicus brief in support of California's same-sex marriage ban. The children's book submitted by Parents and Friends of Ex-Gays & Gays (PFOX), titled "Alfie's Home," is written by Richard Cohen, a self-professed sexual reorientation specialist who tours the country talking about his therapy -- something he says can help gay and lesbians "change their orientation." PFOX is a group that argues that homosexuality can be "cured" through therapy or self-determination, the Washington Post notes. In the brief, PFOX addresses the question of whether or not the Equal Protection Clause of the Fourteenth Amendment prohibits the state of California from defining marriage as the union of a man and a woman. PFOX argues that gays and lesbians can not be part of a "protected class" because being gay is a choice.
