I don't see anyone on this thread alleging that sexual assault or harassment by Weinstein or anyone else was in anyway ok, but when anyone is in a harassment (as opposed to forcible rape or assault) situation, they have a choice to walk away, despite the costs to their career.
There is so much consensual transactional sex in the entertainment industry (sexual favors for career advancement) that until that is considered unthinkable by *all* women, those women who won't engage in it are going to be at a disadvantage in their careers AND men in the industry are being conditioned to think that there's a good chance they'll get some in return for career advancement. That doesn't make any of what Harvey Weinstein did right, that doesn't make any of the women who were attacked, harassed, or otherwise abused by him at fault, but we need to acknowledge that they were victimized primarily by Weinstein and secondarily by culture in the entertainment industry created by those women in the industry who believe "sex is one of the weapons in my arsenal for career advancement."
It's also a little disturbing that a few of the women who are coming out are using Weinstein's physical grotesqueness as one of their primary talking points (i.e. "he looked like Jabba the Hutt"). That reads dangerously like a primary objection to his behavior comes from how he looked, not because they are objecting to the behavior qua behavior. It reads like transactional sex would have been ok if he were better looking. And that's a huge problem in and of itself.
Those who are saying on this thread that "maybe they wouldn't have gotten their career, but they DID have a choice" are also correct regarding those who were not physically assaulted by Weinstein (i.e. the requested massages, him taking off his clothes, etc). If he wasn't engaging in forcible action - and he seems not to have engaged in that in all of his sexually harassing interactions -- a lot of women were in a position where they did have a choice to walk away, to tell him off, to go to the police, to not put up with it. Yeah, maybe it would have cost them their career, and that's why it is so dicey to report sexual harassment. But they did have a choice, and a lot of them decided their shot at stardom was more important than (1) protecting other women from this behavior or (2) trying to get justice for themselves.
So yes, Harvey is the wrongdoer in a civil and criminal sense, and no one who was assaulted or harassed should be blamed for BEING assaulted or harassed, but blame can attach (1) to the things people who were harassed or assaulted chose to do (or not do) after the fact, although that would require that we know their motives for staying silent (i.e. if it's trauma and fear, that's one thing; if it's "I decided my career was more important than reporting" then, yeah, part of the problem and is a blameworthy thing) and (2) to anyone who engages in transactional sex to further their career, because that creates a culture where it's expected.
