He appealed to Childline's directors and to the chief executive of its umbrella charity, the NSPCC, but his appeal was rejected.
An NSPCC spokesman said: 'Volunteers cannot give the impression that Childline endorses their personal campaigns.'
Last night Prof Weston of the Metanoia Institute said: 'When he was a student Mr Esses made a series of public pronouncements.
'In doing so he brought the institute into disrepute and made his position on the course untenable.'
Kicked off his course and off Childline for holding a belief which is now protected by law.
This should be interesting.
He's calling the current climate a watershed moment and he's right.
The public should know he launched an online petition in May called 'Safeguard evidence-based therapy for children struggling with gender dysphoria' and the NSPCC terminated his position calling it an 'inappropriate personal campaign.'
This from the charity with statutory power who saw nothing wrong with an employee wearing a gimp suit, masturbating in the toilets and uploading the video for further consumption. And complained at the criticism levelled at them calling it homophobic.
I seem to remember other people being concerned about the lack of boundaries from trans affirming Childline volunteers too.
Meanwhile, the way some fellow Childline counsellors were handling calls caused him alarm.
He felt they didn't explore properly why children were unhappy with their gender.
Instead, they simply 'affirmed' their belief to be transgender.
Mr Esses said: 'They would just go through the motions of affirming their transition with no form of exploration whatsoever.
Digging.
