Each culture has expected certain values, attitudes, and ways of facing existence from a person born biologically male, which had to be fulfilled in order to be fully accepted in the community. However, anything that deviated (and still deviates today) from these norms had to be sidelined, annulled, or corrected at best, as was the case with people who expressed a sexuality different from heteronormative patterns, or a divergence between their biological sex and the one they felt they belonged to. The work you hold in your hands offers, for the first time, a deep and rigorous analysis of transsexuality, including a historical journey from Antiquity to the present day, with all the political and social changes that have occurred, also detailing the evolution of mentalities and the political and social struggle of homosexuals and transsexuals to claim their legitimate rights. This essential text also includes numerous testimonies from transsexual people that reveal in all their harshness the slow but inexorable change recorded in our country, and even references the evolution that has taken place in other nations within our cultural sphere; all these changes will decisively influence the adaptation of laws, social perception, and the treatment that the media currently give to transsexuality. In short, a book more than necessary, an expression of an aspiration for justice.
