I don't think you have to be a feminist to say Ellison is acting like a jackass. I don't think it's being overly protective of women to call a fatwa on his ass. I don't think it's unreasonable to say that we need to make an example out of Harlan Ellison so that from now on, fans and pros alike will keep their God-damned hands to themselves in public. After seventy years, fandom finally has a sizable number of women interested in the field, but we now have immature "enfants terrible" pissing in the ice cream. It's got to stop. If people like Harlan Ellison can't behave like civilized human beings, then they should just stay home and stay the hell out of fandom. If Harlan has some kind of problem with alcohol, drugs, or some chemical imbalance in his head, I don't care. It's on him to deal with it and quit being an internationally infamous pain in the ass instead of yukking it up and going out of his way to build on his already shitty reputation. He can behave when he wants to (see con reports from this year's Minicon), so I don't think it's a matter of can't behave, it's a matter of won't behave, and it's long past time to call him on it.
So what is to be done? Harassing him at panels would be great if he hadn't preempted that by announcing that LACon was going to be his last convention. Boycott his books? Too little and too late, though every little bit helps. Most of the other suggestions I've seen are cute, but either ineffective or illegal. About the only option left is to hit him where he really lives: in his enormously overinflated ego. There's no question that the man is an outstanding writer. He's won buttloads of awards for it. Odds are good that none of those will be revoked, since the awards are for the work. However, he has been named a Grand Master by the SF Writers of America.
Has it occurred to the SFWA membership that Ellison's conduct - and their silence about it - makes them look like a bunch of misogynistic fucktards? (Yes, I'm well aware that SFWA has female members. Duh.) It seems the least they could do is censure him for this kind of behavior, if not actually revoke the award. The least we can do as fans is lobby them to get it done. Here's hoping SFWA can take a hint.
UPDATE: Maybe this is the reason he's not going to conventions any more. Must really suck to have The Fastest Tongue In Fandom for all those years and then get pwnz3d by a cartoonist who has no idea who you are and could care less because the first impression you made was: "Hi! I'm an Enormous Gaping Asshole and Bully!" (Scroll down to the 8:46 PM post by Gabe or ^F for "The story".)
