The situation is, TransParentlyAnnoyed , you know some young people with gender dysphoria who reacted as you describe; I know other young people with gender dysphoria who reacted differently and became reconciled to their natal sex, and went on to live their lives as such.
Both these experiences are anecdotal, and ' I know somebody who.... my child says.... my own experience is... ' are interesting and significant, but they are just your personal experiences or my personal experiences, and they point in different directions.
That's where properly-conducted studies are useful, and a number of studies show that gender dysphoria in children is more likely than not to be temporary, and the majority will, with the passage of time and without any medical intervention, accept their biological reality.
It is an emotional subject obviously- I get emotional when I think of vulnerable gender-incongruent children like I was, being told that if they take X or Y or undergo Z, they can change their sex, when in fact that they can never be anything other than the sex they were born into.
I believe that children deserve the truth about biological reality, and all the love and support they need to live that reality.
I base this on my own first-hand experience of growing up, and through, and out of, gender dysphoria in childhood.
You and I, TPA, have come to different conclusions based on our anecdotal experiences.
Judging from your posts on several thread, which are often very negative, using words like 'transphobic' or 'aberrant' etc., you seem to think that your conclusions are more valid than, for instance, mine.
