Because KN has decided to make education a political matter.
The way she's disparages other educators and headteachers saying most are "lefties" is disgusting.
She only ever talks about discipline, punishment, rules and politics when discussing her school.
We never hear about enrichment, performances, sports achievements for school teams or creative achievements of her pupils.
She does talk about how so many choose to hand their mobile phones into school to keep safe for months at a time so they are distracted by them.
Her pupils aren't disciplined. They are brainwashed.
My ds managed to train 16 hours a week at his sport, manage his mobile use, achieve GCSEs including 8/9's and a T level merit (a level equivalent of BBB). All this without getting a single detention throughout school - and also having a rare degenerative neuromuscular disorder and autism and having some learning difficulties.
He has much more realistic view of the world than a Micheala student who doesn't understand that forgetting a rubber isn't a crime necessitating punishment and who hold themselves to such ridiculous standards of perfection at some point they risk MH difficulties when they realise it isn't sustainable or who won't be able to cope in RL when they need to socialise, make personal choices and manage their own time with confiscation of items.
KB thinks she's something she isn't.
I've met far better HT in my time with much more able and well rounded students than hers.
