Blogwrath attended the event and posted a detailed account which includes a video clip of the audience's engagement with the panel during the Q&A. Very interesting!
As Blazing Cat Fur observes: "it went downhill pretty fast".
It's easy to see why the audience was disappointed.
Update: In the comments, Fred Litwin responds:
This is a completely erroneous account of the meeting. There were over 120 people there, and a few were rude and complained. What the video and description doesn't show is the many people who came up to me after the event to thank me...far more people than were enraged by my criticism of Pamela Geller. The audience was not disappointed.
