The rate of attempted suicide in transgender people is over 40% if they are not socially supported. That rate drops to general population levels in trans people who have familial and community support when transitioning.
Long-term the evidence is the opposite. Claiming that the difference between long and short-term outcomes is explained by the difference between support levels is not science. It is guessing.
"One hypothesis, the social stress model—which posits that stigma, prejudice, and discrimination are the primary causes of higher rates of poor mental health outcomes for these subpopulations—is frequently cited as a way to explain this disparity. While non-heterosexual and transgender individu- als are often subject to social stressors and discrimination, science has not shown that these factors alone account for the entirety, or even a major- ity, of the health disparity between non-heterosexual and transgender subpopulations and the general population. There is a need for extensive research in this area to test the social stress hypothesis and other poten- tial explanations for the health disparities, and to help identify ways of addressing the health concerns present in these subpopulations." https://www.thenewatlantis.com/docLib/20160819_TNA50Sexualit...

Reimer's socialization was a lot more traumatic than being told he was female. The wikipedia article only touches the surface of the disturbing abuse he was subjected to.
I don't see why this story would lead anyone to accept gender identity.
I also think there are many millenials and gen-Z's who would be classified as "TERFs", and in fact would view the term as derogatory.

*Edited to be less snarky
Did Janice Raymond pass away? Did you mean Mary Daly?
This was an early factor in third-wave feminism accepting gender identity, which is why almost all millenial and gen-Z feminists accept trans and intersex people and why TERFs tend to be older (or deceased, good riddance Janice Raymond.)
I've found that the left tends to distrust science that may contradict its ideology, and the right tends to distrust experiences too alien from their own. In Reimer's case, the science had a human tragedy at the center of it which bridged the gap and led to change.
