The political correct ideology was born in the defeat of the radical wave of the 1960s, and the sour whiff of failure hangs around it to this day. The middle-class left retreated into universities and other public sector ghettos where they could pretend the outside world didn't exist. There they could set their own speech codes on racism and sexism and force doubters into silence.
I love the reference to universities as public sector ghettos.
What happens if there's a hitch and the children don't start swearing, and in particular fail to come-up with homophobic abuse? The campaign instructs that this disaster can be averted by the teacher saying: 'Well, when I was on playground duty I heard one boy call another a "poof". I'm going to write that up. Now can you think of any more?'
In other words, the children must be made to fit the campaign's stereotype and teachers must be encouraged to find prejudice where little or none exists.
