This ideology has infested State schools root and branch. 
But try going past a private ( "posh") school when the kids are coming out sometime.
Not a blue hair to be seen. Boys and girls in traditional uniforms, boys in trousers, girls in skirts. (I'm NOT saying that conformity is a good thing either).
Notice that it's we, the taxpayers, who are funding this nonsense.
