Transidentity, or “Transid”, refers to types of identity that feel at odds with a being’s current circumstances, most often biological body, and are experienced in a way closely comparable to being transgender, such as with emotions of dysphoria and/or euphoria, or a desire to transition to whatever extent is possible with current technology. Some of the most common include transspecies, transage, and transrace. Many beings who have one or more transids are also transgender, and consider the experiences comparable from firsthand experience of both.
Transspecies beings identify with a different biological species. When that species is an Earth animal such as a cat, dog, fox, wolf, etc., they might refer to themselves as “therian”. Non-species identifications such as robots, zombies, or vampires are typically called otherkin, but the experiences are mostly similar. Transspecies beings may approach species presentation in ways such as learning to make animal sounds, adopting animalistic body language, wearing animal ear accessories, or using species-focused neopronouns like pup/pupself.
Transage beings identify with an age other than their chronological one, and can be older-to-younger (OtY) or younger-to-older (YtO). Depending on the individual, this may be focused more or less on different age-associated traits, such as physical features, social treatment, mental state, numeric year. A Transage beings might present their age by using makeup to conceal or mimic features of aging, wearing clothing culturally associated with their identified age, or allowing themselves to behave more similarly to their idea of that age.
Transrace beings identify with a race or ethnicity other than their native biological/cultural one. It’s still sometimes debated whether “transrace” or “transethnic” is a more preferable term, but “transrace” is more common. Methods of presentation can include getting cosmetic treatments to alter appearance to more closely resemble the identified race, learning to speak another language, dressing and decorating in race-affirming ways, or studying ethnic history.
A very large number of other transids exist, ranging from broad scopes such as transchronological (identifying as someone from a different time period) to very specific traits such as transfang. Generally speaking, any way in which a being’s traits differ from their self-conception can be a transid or part of one. Unfortunately, beings with transids are often subject to bigotry effectively identical to transphobia or transmedicalism, with directly analogous arguments and insults, even from beings who otherwise oppose transphobia/transmedicalism but don’t recognize the double standard.
