But there are several kinds of IDENTITY other than just "gender Identity" that make up our psychological identity profile. There is "Personal Identity"---That is Me vs you vs him or Jack doe vs John Jones. There is Human/animal Identity, and even inanimate vs anamate identity
A kind of HERARCHY exists to the Identity components. The basic is Animate vs animate "I am a living being--not an object" Then comes Human/animal "I am a human being" Then comes Gender "I am a male(or female ) human, Then comes Personal " I am John Jones" ===There may also be a "sexuality" identity component(not as definate). ie, Homosexual vs Hetro---That would be between the gender and personal identity in the herarchy.
Here we can see that "issues" at different levels of identity can result in different "eccentricities" in humans. Obviously, Most CD and also TS can be traced to the gender identity level, although, as am "escapist CD" I see it in the personal level, myself. as my main point is to be "not me" rather than a "fem me"--I think ACTORS also operate from the Personal ID level--although they may not all be CDing--- I See MY CDing is a tool to make a more intense ID break.
The humam VS animal ID is very similar to the gender one---"Transformationists and "furry" types have their issues here. The "turned to an object, petrification and fetish types may be messing with their Inanimate/animate ID.
Studying aspects of identity is quite facinating.
