That quote exposes the problem for the Fuhrer and his party; that they are fundamentally too extreme. The reason for the BNP’s increased vote is due to widespread disillusion at the major parties (Labour, Conservatives, Liberal Dems) and the extensive corruption that their MPs have shown. Hence, the increased support for the BNP is more of a protest vote than anything else. But when Nick goes on national television and gives openly sympathises with one of the most infamous white supremacist organisations in history, that create serious problems of allegiance for all BNP voters outside of the hatecore bonehead supporters.
Nick, in his Holocaust statement was clearly trying to have his cake and eat it too: not explicitly denying the Holocaust, but still sending a message to the Brownshirts watching at home that he’s still a died-in-the-wool anti-Semite.
That's why I think giving the BNP this sort of publicity is needed, as it exposes the Party for what it is: a front for neo-Nazism. Gordon Brown stated “We’ve got a duty to expose the BNP for what are racist and sectarian politics.” I agree entirely; give Nick enough time on air, and the BNP’s support will implode harder than One Nation (although hopefully for different reasons).
