The thing about MZB and separating the work from the artist… is that there isn’t really a separation. I’ve been following a sporking of Mists of Avalon, and it’s basically one long rape apologia tract. Like ~mystical~ magic pagan rituals that include "The little blue-painted girl who had borne the fertilizing blood was drawn down into the arms of a sinewy old hunter, and Morgaine saw her briefly struggle and cry out, go down under his body, her legs opening to the irresistible force of nature in them. ", and this is treated as all fine and wonderful and mystical. Deeply, deeply creepy stuff, both as subtext and occasional outright text.
Yeah, Bradley’s Darkover books are deeply horrifying in hindsight: there’s also rape apologia, redeeming a pedophile, etc. But it and Mists of Avalon are still fanatically defended by some who cling to the “feminist” aspects (mostly the Free Amazons stuff for Darkover) while blindly ignoring all the awful stuff packaged along with it.
Given that Darkover uses a lot of names and stuff from The King in Yellow, which also influenced H.P. Lovecraft (“Hastur”, “The Yellow Forest”, “Carcosa”, “the Lake of Hali”, etc.) I’m not sure it was intended to be a happy place, even in time periods that weren’t the Ages of Chaos (whose name alone should give you a clue they were horrible times). In other words, to my mind there were some markedly dystopian things going on in them, so some of the so-called “rape apologia” didn’t strike me as such, it was just horrible crap happening in society trying to survive on a marginally habitable planet. In other words, “awful stuff packaged with it” seems appropriate for a setting where the aristocracy puts up with a lot of dead kids (or kids that need to be put down for the sake of everyone else’s safety) in order to hang onto power and the peasantry lives a pretty desperate and hard life between the chronic forest-fire problem, deadly critters/aliens, fellow humans warring over very limited resources, and iffy agricultural prospects. You have stuff like mind control, horrific weapons of war, forced breeding of people, forced breeding of animals, forced crosses between animals and people…
It’s not a pretty place, Darkover… never had been.
Yes, if anyone had reversed that, and a Man ditched his decent loving wife as she wanted children, he would be castigated as the worst kind of cad.
Instead Gilbert is held up as a hero and made wealthy.
Really? Then reverse the sexes in Eat, pray Love.
I agree, unless you are sexually harassing people or being a racist, just simply being a diva and even a asshole is not really horrible.
The OP’s examples of men who were horrible people were not men who were/are mere artists, but were in positions of power and authority: Roman Polanski (director), Woody Allen (director), Phil Specter (music producer). That’s different from artists who are/were difficult to work with.
There are fewer women who’ve been in such positions, but I have a nomination: Roseanne Barr, who among her other credits, has been a producer. I think it’s pretty obvious why she should be on the list.
I think it was the heat in the limo, but same difference. And I’m not sure whether the issue was that she didn’t want to speak to the “peon” or whether she was so terrified of a confrontation that she got someone else to ask for what was objectively a trivial act. Battle had some anxieties bordering on paranoia for a while, hence also her “don’t look at me” demands.
Personally, I think cases like Vivian Leigh where she was apparently dealing with a severe mental illness are different than someone just being an awful person. For example, many people with bipolar disorder become hyper-sexual when they are in a manic episode, so I don’t think we can judge her for cheating on her husband when there is a good chance that her illness was a major factor in why she acted like that. My sympathies are with anyone who has to live with a serious mental illness like bipolar disorder, because it has to be incredibly shitty to have an illness where the symptoms affect how other people perceive you as a person.
If we’re including non-fiction authors in this conversation, I would say Sarah Jeong qualifies as a pretty awful person based on her tweets and her comments that show a pattern of racism against white people.
I also see there are now allegations that she publicly exposed a rape survivor’s identity knowing that it might lead to the rape survivor being harassed. Whether or not you think she deserves to be fired for her behavior (though I personally think that anyone who makes such comments about race should be fired), she certainly doesn’t seem like a very nice person.
That link doesn’t have any comments from the person you are referring to, it’s a whole lot of “she should leave” stuff from other people. 
Artist Peregrine Honig is widely loathed in Kansas City, but I’m unsure how well known she is outside of KC. I do know that her only artwork of any fame, “Two Fauns” was not credited by her in any way. The “sculpture” was a piece of taxidermy bought in a shop, and the photograph created by another artist. Which makes her an artist only if you take Jeff Koons seriously (which I do not.)
