I actually think it was reasonably civilised, the audience could have been much worse behaved than they were - and a properly balanced debate dealing with these issues would have been very difficult to stage. Griffin's problem is that he has made such outrageous statements in the past (he admits to his earlier holocaust denieal views) that it is very difficult for him to regain any sort of credibility - it provides his opponents with the convenient weapon of "opportunism" and insincerity, with which to challenge his supposedly more moderate stance.
Jack Straw was awful, rambling, incoherent - he just didn't seem to know how to handle Griffin. I thought the other panelists dealt with it reasonably well. Even Griffin didn't emerge from it too badly, although I doubt whether he will have convinced many people that he has become any more reasonable or moderate. Bonnie Greer made a couple of delightful off-the-cuff remarks.
What gets me though is the awful way the press has reported it. Organs as diverse as the Mirror and the Telegraph have misrepresented things which Griffin said. For example they say he defended the Klu Klux Klan, and attacked homosexuals. I was listening carefully, and I think he actually skillfully avoided doing either (whatever his private views).
Wrt the Klan he stated that the particular group he was dealing with was a non-violent one, and did not state (as is implied in the papers) that the Klan as a whole was non-violent. He was also claiming (rightly or wrongly) that he was appealing to their supporters to change their views, rather than the Klan leadership which does not sound like "defending" the clan.
According to the Telegraph, he described homosexuals as "creepy". He didn't. He said (I paraphrase) he found men kissing each other openly on the street creepy. I'm afraid I find that an unpleasant sight as well (which I can't rationalise), but I'm certainly not homophobic and have close homosexual friends (and a lesbian daughter).
I detest Mr. Griffin and all he stands for, but I think the media does us a misservice in mis-representing his actual statements. It's applying the same tactics they would condemn in those they are attempting to demonise.
