I bow to yours and Richard Bridge's clearly superior knowledge of the far right in the UK. Unfortunately all of Tim Hague's posts bar one seem to have been removed (unlike, strangely, those of the avowedly BNP 'Sam'), so I can't really comment now. All I do see is a massive assumption.
I happen to agree with him that none of the mainstream parties has done anything significant to boost, encourage or endorse traditional British culture, leaving the field open for the BNP. For me the comments of Labour minister Kim Howells that his idea of hell was three folk singers in a bar marked rock bottom. You can split hairs over who offered what limp support to opponents of the Licensing Act, but it doesn't convince me that any party gives a flying fart.
Still, you'll probably assume that I'm a fascist for disagreeing with you. Now that that would be a lark!
