Since the middle of the 1900s, some psychologists like to use "homosexual transsexual" (to mean the same as straight transgender woman) and "heterosexual transsexual" (to mean the same as transgender lesbian). Biologist Bruce Bagemihl is against this. It is because Bageminl thought it makes it simple to say a transsexual is a homosexual male looking to run from stigma. The term "homosexual transsexual" is "heterosexist" because it describes people by sex assignment and not gender identity. Sexologist John Bancroft says he regrets using this language. It was normal at the time Bancroft used it to talk about transgender women. Since 2008, he attempts to use terms that do not hurt the feelings of anyone. Sexologist Charles Allen Moser is also against any terms like that.
