*sigh* Me, I wasn't there. All I know about it is what I heard online "Did you hear? Harlan grabbed Connie Willis' breast!" Um...yeah...and in front of hundreds of people (or so I assume). I can see this happening several ways, from the deliberately offensive, to the joke that went over like the proverbial lead zeppelin. And I think that if Connie Willis was offended by his behavior, and wants an apology, it is hers to ask for. And I am equally certain that if she was offended and tells him, that a sincere apology will be forthcoming (if it hasn't happened already). I don't think that the online lynch mob that wasn't even there deserves an apology. There are a lot of folks out there who "hate" Harlan Ellison...and most of them have never so much as been in the same room with him.
Harlan has offended a lot of people over the years, and I can understand why. Having spent some time with him behind the scenes at a book signing one day, I got to watch him metamorphosize into "ranting and raving Harlan Ellison". But behind the scenes? People don't believe me when I say that I thought he was sweet. And maybe because he was nice to me, I am biased. But what if the two lines online were "John Scalzi grabbed Connie Willis' breast. The audience was horrified." Or "Patrick Nielsen Hayden grabbed Connie Willis' breast." Would the wolves be howling for blood, or just saying "Dude, that was *so* out of line"?
