According to the poster it is. And, it represents the view of 300 individuals total, again according to the poster.
As for CAIR -- I'm not sure if that was the group the leader belonged to, just a guess (but I believe it was). I watched the show in passing while in Germany and wasn't taking notes at the time. I did note the same speaker was interviewed earlier in the International Herald Tribune and was in the UK meeting with European muslim leaders. He pertty much came out and said that muslims have to come out of the 14th century and get with the modern world -- especially those communities in Europe.
As for links to HAMAS, he addressed that saying he disagreed with the terrorist elements but found it hard not to support the hospitals etc. when there were no alternatives to serve those communities. His overall message was not positive to radicals by any stretch of the imagination, was anti Jihad and pro integration into the general culture of the West if you are living in the West. For example, where wearing burkas is concerend (a big issue in Europe and one he was grilled on) he supported the general individual right, as I recall, but saw the real secuirty concerns and the degree with which it creates problems with assimilation in society. Really, a call for Muslims to have some common sense on the issues and to work as part of the system instead of outside of the system.
He seemed very moderate.
