Almost every trans I've seen in a documentary argued they are trans because they liked things society conditioned us to believe belong to the other respective sex. They will in 90% of the cases argue that because they liked dolls, dresses and princesses growing up they must have been born in the wrong body.
This reinforces and perpetuates negative, regressive and harmful gender stereotypes and supports the notion that there is such thing as "innate female/male behavior". It also subordinates itself to a restrictive binary gender view. Young men and women no matter their behavior should learn to express their isms and identity with the body they were given and live in unisono with actual reality.
Lastly the suicude rate for "trans" ppl post or pre transition is the same. So transition is no solution of cure for ppl with non-gender conformative interests of behavior.
A world where gender isn't held to such importance is a world without trans. And that's the world I personally wanna move towards.
