This is a fairly good, quick, succinct rundown of gender identities. There may be some disagreement about who falls under the term “transgender,” which is the last category discussed. According to this video; cross dressers, drag kings and drag queens are all under the transgender umbrella. I think it’s fair to say that the inclusion of those individuals as transgender is controversial. Particularly because those are more often seen as gender expressions as opposed to gender identity. That being said, if these individuals feel that their gender identity is other than cisgender, then I have no problem using those terms in addition to their gender identity. For example some trans women may also be drag queens but it is clear that drag is expression and performance while being a trans woman is their gender identity.
