I don’t know how much truth there is in Jolyon’s claim of an increase in deaths of children on waiting lists, but even if there is an increase in the death rate, without information regarding what caused those deaths, it is dangerous speculation to use them as some kind of “gotcha” by the unproven claim that it was caused by the ban on puberty blockers.
Apart from any other considerations, during that period there was a worldwide pandemic, with lockdowns which likely worsened the mental health problems of many young people and made it harder to access care of any type.
As was mentioned upthread, irrational parents and children are buying illegal medications from the internet.
The most sickening thing is that this is a manufactured psychological phenomenon, where children are being told they are likely to commit suicide if they don’t get their way. If there was a natural phenomenon, where children were so distressed about their sex that they committed suicide, it would have been recognized long ago. If there has been a rise in suicide, it is manufactured by those who are pushing the medical model of child transition.
