Alan Johnson commits polytoynbeeism

Last summer I identified the concept of polytoynbeeism:

You divide the world into two groups: there are sensible people like you and your readers, and there are people who hold ludicrous views. There can be no middle position.

There was a good example of it today in Alan Johnson's comments to the UK Youth Parliament:

He told the UK Youth Parliament that exams were not getting easier and critics were sentimentalists harking back to a "mythical golden age".

So there are sensible people who agree with Alan Johnson, foolish people harking back to a golden age and no position in between?

You only have to type that sentence to see what nonsense it is.
