Lostart, childhood transitioning is a tricky area.
On the one hand I know that it is possible to be aware that you are trans at primary school, as I was. On the other, that you do not really understand fully what is happening until probably you are around the start of puberty.
The high drop out rate of those who switch gender as young children shows that often it is just experimenting or being a child or role playing. All healthy parts of being that age. And so it would be disastrous if we overplayed this hand with children because it could create (and I suspect is creating) situations where peer pressure and social contagion are playing a part in the sheer number of children who are considering these things.
Quite clearly this leads to two conclusions.
Firstly, that you have to be very, very careful and take it slowly. Nothing drastic should be done quickly. And that includes blockers. Give the child time to find themselves and grow out of it. As it looks as if many will.
Secondly, find a way to properly identify which children are in that small percentage with real and deep gender dysphoria. There is plenty of data from transsexuals most of which knew something was wrong by about 3 or 4 and what that something was by about 8 or 9. Child psychologists and social workers should carefully assess those cases and blockers do not need to be an issue that early anyway.
We certainly should not be issuing blockers lightly. We also don't know enough about any possible long term consequences and that research is urgent. I do think that there is a case in rare instances where the depth of dysphoria is obvious and has been repeated and persistent over several years to consider this route.
Because it can make such a huge difference and is a one off opportunity where you cannot turn back the clock once you miss the window. But equally you also have to avoid any inappropriate consideration as it will be tempting to do that too often.
I am not opposed to blockers per se. If they had existed in 1961 I would have wanted them 100%. And they would have really helped my life in many ways. However, I also know that the risk is real of using them where they should not be and creating a disaster. So I am rather split at the moment and think we need more study first. And I definitely believe in 90% of cases they should never even be considered and probably if they are considered should require a judicial review first to ensure all aspects are thought through.
I am also 100% sure that nothing that we know is irreversible - which means cross sex hormones and surgery - should be sanctioned until the child is legally an adult.
