This is mostly a note to myself, and written perhaps more to clarify my thoughts to myself than for anything else.
Trans consists of actually being something of some other sex, or gender, than the sex, or gender, assigned to you at birth, or later, by others.
That's about it, really!
Trans is thus a problem of other people - the core of the problem being the forced assignment of sex and gender, and the (misplaced) faith of the majority in the correctness of the communal assignment.
Trans becomes a problem for the trans person hirself only if other people make it a problem.
This can happen by ungendering, misgendering, physical violence, denial of necessary facilities, denial of medical care - this is not an exhaustive list.
The problem is not trans. It's the oppression.
(the headline is a nod to Einstein, in case you wondered).
