Matthew Syed thinks the BNP should appear, on the Millian grounds that:
Which raies the question: where are the arenas which do permit a sufficient exercise of public reason as to expose the BNP for what they are? Of course, there are websites that do this, and occasional reports, even from the BBC, that do so.
What we lack, though - especially outside the internet - is an infrastructure or culture that can underpin deliberative democracy, and can improve public discourse. The BBC seems to think its job is to merely reflect a public opinion which has been debased by its private sector rivals.
Without such a public sphere, the BNP - far from withering from the oxygen of publicity - might actually thrive with it.
In this sense, the question of whether we should give a platform to the BNP is a knotty one precisely because the institutions needed to sustain a truly healthy democracy are weak or even absent.
