Charlotte is a Barcelona resident and a licensed Human Rights Investigator. She is the person who developed theconcept of Síndrome de Harry Benjamin, and in 2005 founded the first HBS organization.
She maintains that HBS is an intersex condition developed in the early stages of foetal development, and that an HBS woman is not a transsexual. She is further contentious in that she and her movement has become known for its disparaging of other transgendered persons, even post-ops, and GLBT persons in general.
Lynn Conway, Andrea James, Calperina Addams and Marci Bowers are also disparaged on her forum in that they not anti-transgender. Charlotte has approved of the situation for transsexuals in Iran. She regards the term ‘transsexuality’ as pejorative in that she takes it to imply a choice.
Some HBS activists have since split with her.
Charlotte sometimes uses the name Charlotte T. Guren, and wrote to Laura Amato that Guren was the name to be used, but SHB-Info.Org still calls her Goiar, and she had a Myspace page as Goiar until early 2009.
