A woman getting hit back is always something that brings up raw emotions. Rather than talk about what sick fucks people in this thread are, how Gor is doomed because (I really don't even know) and cast aspersion on the squickiness of other posters based on not having even been interested enough to listen to the audio (there is no video), maybe we could dial it back a bit? Just a little?
The only things that are known about this incident are:
The audio recording is of two obviously drunk people, one male, one female.
The female screams and wails throughout, loud enough to be unintelligible.
The male responds with derogatory names and insults.
At some points it sounds like there is physical confrontation.
After the fact, the male posted to one of his social media accounts to say that he was drunk, she hit him first, he "had to do what I did". He also says in another message that he "hit her and fell on top of her and hit her again".
Unless contradicted by both parties present to the extent that securing a conviction would be impossible, it is likely that law enforcement will pursue charges if they're able to locate the man in the audio (and prove it was him in a court of law).
Nobody has suggested that BDSM or Gor or role play are involved here. The point being made (I think, and I can be corrected if wrong) was that many people in this community, and in BDSM communities, tend to have relationships that other people would find, for whatever reason, unacceptable. Some people have practices within their relationships that are, in many states and/or countries, illegal. In some countries and states, your consent to being spanked, flogged, beaten, spat on, bound, "play-raped" etc. means diddlysquat in a court if you're caught doing it. So if you're unlucky enough to get on the wrong side of a previously good friend, or a nosy neighbour, or an internet hate mob, it doesn't matter if you're Mr. Consent himself with a signed and dated contract, or Mr. Asshole Abuser punching seven drunken bells out of his partner - in the eyes of the law, you're the same.
And to some people in some circles, the woman who is allowing herself to be beaten by the drunken asshole abuser and the woman who is allowing herself to be flogged by Mr. Consent because she gets off on it, are the same - one of them is suffering from battered person syndrome and the other is a victim of her own internalised misogyny. And if you're prepared to say that the former (battered person syndrome with the asshole drunk) is a valid reason to erase a woman's agency and insist that she be forcibly removed from a situation you don't find acceptable (and the asshole abuser jailed, even if he was reciprocating), why is it not also valid to say the same for the latter?
To wit, the point was not "many of us are into BDSM so we should be cool with some spouse battering hurr hurr" as I read it. It was "many of us are involved in relationships that might push the boundaries of acceptability for many people and are potentially at risk of being similarly hounded and/or prosecuted based on other people's disagreements." Where are the ethical boundaries? Who decides?
And to take that question further, for me, at what point does the "concerned internet citizen" overstep? Was it when Anonymous took over his instagram account? When he was told to kill himself for the fifth time? For the five hundredth? If he follows that advice will everyone be righteously happy that a dude who's apparently recently lost his dad and made a mistake for which he has apologised is now dead? What if it's true that she hit him first? Does it change anything? Does it matter that nobody knows whether she did or not before going after him as the devil of the day on 9th May 2016?
Sure, you do dumb shit publicly you expect to catch some flack for it, but when so little is known, the baying mob of vigilantes can be a bit much.
