there was a document?
If that was sarcasm, it's 5:39AM and I've been up since 4AM, so it's flown right over my head.
If not, Headcrab Zombie linked a document which is in the quote in my post. It specifically mentions;
Gender: refers to the attitudes, feelings, and behaviors that a given culture associates with a person’s biological love. Behavior that is compatible with cultural expectations is referred to as gender-normative; behaviors that are viewed as incompatible with these expectations constitute gender non-conformity.
Gender identity: refers to “one’s sense of oneself as male, female, or transgender” (American Psychological Association, 2006). When one’s gender identity and biological love are not congruent, the individual may identify as transloveual or as another transgender category (cf. Gainor, 2000).
I'm not sure what "transgender categories" exist, but I'm certain that they're probably not as crazy or wild as some people out there who want to be special would have us believe.
