To me, if I chose to build a party based on the idea that all religious people should be made to wear a hat at all time, catholics bowler hats, muslims fedoras, etc, and Question Time thought it'd make amusing TV to let me on to show just how nuts I am, then where's the problem?
I'll be truly shocked if Griffin isn't utterly destroyed by this debate, considering how hard QT can be on regular politicians without anything to hide.
I get the feeling the people protesting are thinking he's going to get on Question Time and just get to stand there going 'We want all darkies out, who's with me?' and the panel and audience are going to give him a standing ovation. He's not going to get an easy ride, I'm sure of it.
