Homosexualities, presentations forcefully installed in accepted discourses, are a source of controversy in a variety of disciplines. Interrelations between cultural norms, prohibitions, and discourses cannot be ignored, no matter how they are interpreted. The controversies emerge at times of social and cultural changes, some inherent to a certain epoch, others with long-term perspectives and open-ended implications. In Leonardo da Vinci and a Memory of his Childhood, S. Freud presented an explanatory theory on male homosexuality centred on excessive attachment to the mother leading to identification with her and choice of an object of the same sex, just as his mother chose him. He proposes yet another mechanism in Some Neurotic Mechanisms in Jealousy, Paranoia and Homosexuality. He prefers an option that is reactive transformation of fraternal rivalry and hate into love, dominated by homosexual object choice when it is neither sublimated nor converted into tender love.
