“This connection, at once semantic and conceptual, between unorthodoxy and sodomy, was firmly established during the late Middle Ages, and has never been severed. It is as strong today as it was six hundred years ago. To be stigmatized as a heretic or bugger in the fourteenth century was to cast out of society. Since the dominant ideology was theological, religious deviance was considered so grave an offense as to render the individual a nonperson. Whatever redeeming qualities he might have had counted for naught. The sin of heresy eclipsed all contradictory, personal characteristics, just as the teachings of God and the Church eclipsed all contradictory empirical observations. The disease called “mental illness”—and its subspecies “homosexuality”—plays the same role today.”
