To prevent a party that legally stands for British elections from appearing on the BBC would have been used to far more advantage. The man is a manipulator of facts and situations as you can see from his reaction to the way he was "bullied" last night. Far more mileage in whingeing about being frozen out by the 'impartial' BBC if that is the way you work.
Make the party illegal if you want to prevent them from having their say, you can't pick and choose which legitimate political parties can appear on the telly.
What last night shows is a man struggling to make his own extreme views come across in a way that may not seem so extreme at all. He failed with that, and failed to come across as a credible politician or thinker. Too many times he relies on claiming to have been misquoted, then when faced with cast iron evidence relies on claiming he was taken out of context, and if that fails claiming that he did believe that but doesn't anymore.
I think it was a fantastic piece of exposure; not for Griffen or the BNP, but for those of us who thought he was a complete racist who couldn't sugar coat his vile views but had one skill - the ability to deny, wriggle out of and avoid clarifying anything at all. He was unable to slither round direct questions last night, something now known in his political fog as "bullying".
Well done to the BBC for having some balls for a change.
