'Homosexuality is not, in the usual sense of the word, normal. But nor is is, from a pyschoanalytic context, necessarily abnormal. It is different. Because, in all likelihood, of a genetic disposition and a unique set of early environmental influences, some boys and girls grow up to become emotionally attracted to people of their own gender. It doesn't happen very often, and when it does, it is subject to a unique confluence of emotional, psychological circumstances that make very homosexual child as different from his peers as every heterosexual child. Although a war has been waged over this somewhat banal conclusion, it is difficult, it seems to come to any other. We don't yet know the precise contours of this journey, but we know roughly where it goes.'
