This is not a free-speech issue, this is a consequences of free speech issue. I don't know Loren personally, but I enjoy much of his work -- including his parody of a celeb apology -- and believe him that he's not a racist, and believe as well he could make a real contribution here in Greensboro. If so, it won't be at the front of the video session; we will announce a new session leader shortly.
UPDATE: From the comments at LF's blog:
Feldman: Ed, you fucked up. This was a great chance to have a discussion that might actually matter. Not just bullshit about how to use a camera.
Me: That chance still exists, as I had hoped our email and my blog post made clear.
I agree that you are not best-suited at this moment to talk about using a camera. As a user conference, we’ll still have that session, we’ll just get someone else to lead it.
Please consider coming to talk about the other stuff.
Feldman: I’ll pass Ed.
Me: I’m sorry to hear that, Loren. The offer is sincere, and it remains open.
