sums it up

very few of the protesters thought that they themselves, or anyone they know, would be persuaded by Griffin’s seductive arguments (although one woman said she knew ‘one or two guys who might be’). No, it is always ‘the other’ – the working classes, the underclasses, the uneducated – who are seen as needing protection from Griffin’s words by caring, censorious protesters. The main argument here was that we should ‘learn the lessons of history’, as if the masses are predetermined to act in a certain way and to repeat tragic mistakes of the past unless their awareness is raised

The protesters’ combination of hysterical scaremongering about the return of fascism and disdain for the intellectual capabilities of the electorate (not their mates, of course, but everyone else) means they can see only one solution to the BNP: censorship. Afraid of the public, panicked about the future and clearly unconvinced about their own ability to win an argument, left-wing campaigners instead hope that the authorities, in particular the BBC, will exercise moral judgement on the nation’s behalf and deny Griffin a platform.

the bit in bold pretty much sums up what happens when you have a politics/ideology whose only foundational base is politics and ideology itself, one that’s been steadily emptied of all social/material/class content over the last two and a half decades – Hic Rhodus, hic salta!
