The media needs to be reminded that the image of a scale or spectrum of politics from left to right, with centrists in the middle, is just a not-very-useful visual metaphor.
One revealing light is that centrists sometimes also picture it as a circle, with the extreme left and extreme right close together, rather than farthest apart (attempting to 'explain' the fact that some self-described communist regimes have been just as inhuman as fascist regimes).
Maybe the problem with such representations is that they confuse 2 separate things: ideology and blueprints for better societies. It's obvious, isn't it, that centrism is the most ideologically extreme position (it reproduces the world-view of the status-quo) - but at the same time the least likely to favour an alternative blueprint?
The left is the least ideological - precisely because it favours a rational social organisation; the right is the opposite, based on the irrational (favouring over reason 'authorities' like tradition, religion, a strong man).
