From the internet, about Tandora's understanding of what 'trans' is:
Saying that “trans people are people who are a sex other than the one observed at birth” can be considered inaccurate or exclusionary.
It still defines trans identity in biological terms. Framing transness as being a “different sex” focuses on sex (a biological category) rather than gender identity (a social and psychological one). Many trans people describe their experience in terms of gender, not physical sex characteristics.
It excludes nonbinary, agender, and gender-diverse people.
That wording assumes there are only two possible “sexes,” and that being trans means moving from one to the other. But many trans people — such as nonbinary, genderqueer, or agender individuals — don’t identify with any binary sex. So they don’t fit into the idea of being “a sex other than the one observed at birth.”
A more accurate and inclusive way to phrase it would be something like:
“Trans people are people whose gender identity differs from the sex they were assigned at birth.”
This wording avoids reducing identity to biology, includes nonbinary people, and reflects how trans people generally describe themselves.

Now, I don't personally agree with a lot of that, but this is a summary of how trans people would respond to the narrow definition of it being people who are different sex from the one they were born as.
Tandora, do you agree, or do you think 'trans' means what you said it means?
