My passport wasn’t “updated”; it was corrected to reflect my real name.
“Trans” encompasses almost anyone who doesn’t identify with the gender assignment given to them at birth . It is the superset term that includes binary, genderqueer/non-binary, agender, and other individuals who do not identity with they were designated as at birth.
More than mere gender variance, being trans often (but not always!) leads to a condition known as “ gender dysphoria”, where your sense of identity and how society classifies you clash. Sometimes things can’t be done to transition, and others will undergo hormone therapy and gender reassignment surgeries to correct this. Some simply identify as male or female, others fall somewhere in between, sometimes as both, and others don’t identify or even understand the concept of gender.
There is no “one size fits all” approach. Identity is personal, and sometimes grouping oversimplifies our variety of natures. This has pigeon-holed and overstuffed what it means to be a male, females, or something else entirely…rather than letting us be ourselves.
