They added the "Q" for Queer. A word that they are allowed to use but normal folks can't. Kind of like the "N" word allowed by blacks but not by whites. Totally a PC issue, for sensitive folks. In the past Queer encompassed all of them, but now there is sub groups within the whole. Gender confused kids are not considered gay, therefore do not fit within the Queer criteria, etc, etc. Or did I get that wrong? Who knows.
