"why it's so very, very important that we throw away all our notions of harm reduction"
It's not. We should absolutely pursue harm reduction. That includes reducing harm to severely gender dysphoric youth who are likely to experience extreme trauma at going through puberty as their natal sex and likely to have a much harder time transitioning later on.
"why it's so very, very important we throw away all our notions of helping young people to be happy in their own skin"
It's not. We should absolutely do that.
And for the very small minority of young people who may be happy in their own skin by identifying and presenting as a gender other than their natal sex, that should not be denied them.
"why it's so very, very important we throw away all our notions of not making children into lifelong patients"
That's not a particularly well established notion, though is it. It's somewhat binary - people either benefit from medical treatments or they don't. We don't decide it would be preferable for someone to continue suffering in order to avoid them being 'a lifelong patient'. Of course where there are alternatives to medical treatments they should be explored - which is probably why only a very small minority of gender dysphoric young people end up on puberty blockers.
"of why we should ignore whistleblowers"
We shouldn't ignore them. But we should ask where they fit in in the wider consensus of expertise. We should not disregard the majority consensus just because of whistleblowers.
"of why we should deny the pain of detransitioners"
No one has done that. What I have done is shown that (a) detransitioners are smaller in numbers than people here claim or imply and (b) most of them detransition due to social pressure rather than their transition being wrong.
I've never denied that the very small minority who detransition because they made the wrong choice experience pain.
"why you have invested and continue to invest so much time and energy into breaking down ideas of the age of consent"
This is just another lie. I haven't even mentioned the age of consent, which relates to the age at which someone can consent to sex.
If you mean the age of medical competence, again I don't want to break down our ideas of the age of medical competence - I support the Gillick principles which have been established nearly forty years. It's actually posters like yourself who want to break down the long standing legal provisions on the age of medical competence.
