seriously: what the fuck are you talking about? You're conflating specific, awful, obviously horrific cases with a a general term.
So, because Harvey Weinstein and Bill Cosby, all orgies = rape? what the everloving fuck are you on about?
I think he's looking at situations like cults, where people have been put into a mindset where they're more accepting (and some are indoctrinated from birth).
And its not unheard of for people to be imbibing and then end up in sexual situations that they don't entirely want but are not sober enough to really protest to at the time (with some of them knowing stuff like that was a possibility, some people participated in orgies and had to get drunk or high because otherwise they would not have done it but wanted to do it, and then regretted having done it later; so its not like they got high and then had it thrust upon them thus not being actually consensual). For instance, average guys would be like "orgy? that sounds awesome" and then realize, oh there's guys and they you know might kiss, fondle, or even full on fuck you" only they were incredibly naive, but when they're in just like a mass of people they can't exactly stop everything and at the time it might even feel good, and then they realize, oh, I'm not actually into that. Unfortunately there's a lot of guys that claim women are just saying that when they later claim they got raped. And guys can be "well she wasn't screaming "NO" and punching me so she must've been into it, how was I to know that her going dead fish was a signal, every woman I've been with has been like that!" And the thing is, some women were "dead fish", not because they didn't like sex, but because at the time they basically had grown up believing that women don't have orgasms or enjoy sex, so they're just supposed to lay there and let the guy have his fun. It wasn't until they got out of that shroud that they realize "oh, I can have fun too". But women's sexual liberation scares a lot of the diehard conservatives, so any woman enjoying herself is "under the spell" or a witch or some other bullshit.
There are gray areas. Hell, I know couples where one of them really wants to have a threesome so the other will do it even though they don't actually want to and end up so remorseful over it that it ruins their relationship. But then, there are people that are ok with that.
And that's the rub, love itself puts people into mindstates that they do things irrationally. And there's a lot of situations where that has led to some awful stuff. And look at some of the polygamist sects, where in public they do a big show of it being all consensual. Meanwhile he's starting to fuck the teenage daughters, and the women are fine as they think the teenagers can consent fine so its a "beautiful show of his love for them" or some of the other nonsense. And there's people that come out of cults going "at the time I thought it was beautiful and wanted it" who then later, free from the mental cloud they were in, are deeply regretful. And because society already has a strong negative reaction towards polygamy (or even just polyamory), they (the polygamists) view it all the same. When its like well people can be like "polygamy is weird, but ok it works for you and you're clearly consenting to it" but be horrified about the incest/underage part. They just see the general disdain and not that there could be aspects that are actually clearly a different level. If I'm not mistaken, there have actually been cases where underage people were mad when the situation was forcibly altered (meaning, the person sexually involved was jailed for instance). Hell the girl that Bowie took the virginity of when she was like 13 (and he was in his 20s) and then later Led Zeppelin full on kidnapped to keep people from finding out that one of them was fucking such a young girl so they could then legally marry her when she was old enough, looks back fondly on all of that. I think even the girl that Roman Polanski raped is like "people need to just get over it" and I believe might've even said she doesn't have ill will towards him any more. And when the one woman came out fairly recently about how the "butter scene" in Last Tango in Paris wasn't consensual, she was adamant that people not view it as rape.
Hell look at some of the cults where most the people are just having a groovy time, free love and all that, meanwhile the higher up are doing much more nefarious shit. Was it Children of God where they were grooming that young kid (Ricky?) to be the messiah, which included them full on fucking molesting him, and they had slowly started to seep out "teachings" about how including your children in sexuality was some great thing. Which a lot of people in the cult started going "WTF" but others were like "you know, that actually makes sense" because they're not in the right mindset.
And pimps full on use cult tactics on women. Its not just men either. Look up that female wrestler (that the WWE was naming their battle royal at Wrestlemania after, until people started coming out going "she was horrible, and force women wrestlers to have sex with promoters" and all kinds of other shit) or the woman from Smallville that got arrested recently over that fucked up cult in upstate New York.
That's why I see both ways. I see that yes, it can be all consensual and on the up and up. But there's a ton of situations where it might've even started out that way, but turned crazy.
