Sounds like the Brit girls are taking lessons from the American Feminists...
Grooming lessons?
I've never heard of this in American schools.
In the workplace, nasty feminists always form cabals, and they exploit "sexual harassment" policies to harass the men. They make certain that pretty women can't succeed no matter how genuine their work performance.
But at every school I've known, the pretty girls have walked all over the dykes and fuglies. The social structure is too rigid for any other way.
