Child-lovers win fight for role in Gay Lib
Mr Keith Hose, a paedophile - one who is sexually attracted to children - persuaded tha conference of the Campaign for Homosexual Equality (CHE) yesterday to censure its conference committee for relegating paedophilia to a minor role in the conference business.
Mr Hose told the conference, which ended in Sheffield last night, that he himself had enjoyed "a deep relationship" with two boys aged 11 when he was a sixth-former at school. He is a member of the Paedophile Information Exchange (PIE), which is campaigning for the legal and social accepttance of paedophilia. A PIE leaflet states: "We want to dispel the myths connected with paedophilia, and show that most paedophiles desire gentle, loving, and mutually pleasurable relationships. We believe it is inhumane to children to outlaw their sexuality and we support moves to lower the age of consent."
The successful resolution proposed by Mr Hose pointed out that paedophilia was an important subject because "There are many gay paedophiles, in and out of CHE, yet their needs and feelings are ignored in frequent attempts to dissociate them from the gay movement."
