We have had this argument, you are wrong. You unironically point to people in the past who acted like people today without realizing those people a) didn't even describe themselves the way people are now and b) weren't killing themselves over it.
The historical existence of gender as a distinct characteristic from sex isn't even relevant to the point I made there.
You say there is a long track record, show it. If trans people have always existed and not expressing it leads to suicide, why do trans identifying people and suicidality correlate positively? Where is the record of repressed people all killing themselves for centuries?
Firstly, you're asking why a population that's subject to violent prejudice and legal discrimination have a higher suicide rate?
Here is data pointing to a huge decrease in mental distress and suicidal ideation for those who go through affirming care.
Here's another overview.
And if you want evidence for the devastating failure and cruelty of pressuring people to suppress their own identities and forcing them to conform, I suggest you look at the suicides and self-harm associated with conversion "therapy" centres.
You are lying about data that doesn't exist to defend supporting a mass psychosis event killing people and ruining their lives.
The lack of self-awareness here is incredible: to complain that data "doesn't exist" for my position, and then to come out with such a hysterical claim like that for which you can provide zero evidence whatsoever.
You're guided by iron-age superstition and claiming others are experiencing "mass psychosis" for not indulging the same rancid prejudice as you.
