I don't think you've read enough of the accounts from the woman. And there's more coming. Here's the basic formula he's using:

Goes to event (book signing, media event, etc)....scopes out women around 25 years old (he's older than 40)....introduces and smoozes her....two days later, finds her on facebook and asks out on date. Goes on date....mentions that he's into rough sex....invites starstruck woman back home. As soon as he closes the door....BAM. Chokehold. Then close-fisted punches her several times above the ear to the side of the skull. This leaves no marks but momentarily incapacitates the victim....gives a HUGE headache for several minutes afterwards. (up to an hour) 3 of the 9 women who have come forward described this same story.

This is not slapping your dick on a lover's face or smacking an ass or calling your girlfriend a 'whore' while having sex. This is a sneaky way to violently assault someone without their consent. He is PUNCHING THEM IN THE SIDE OF THEIR HEAD. That, is by definition, 'beating women'...or 'assualt'...or 'sexual assault'. And there is no grey area here.

It's retarded to call someone who, without any consent, close-fisted punches a women in the side of the head repeatedly, a 'women-beater'? I don't get your angle here.

We really need to differentiate here. Gian is not being judged because he is into BDSM. That's how he tried to lamely frame it and he'll have no choice but to back off on that now. This has NOTHING to do with BDSM. This is assault. Sexual Assault. Consent is everything in establishing that difference. Gian would like this to be about him liking 'alternative lifestyles'. The BDSM world has already strongly condemned his actions. Blurring those lines....as you are doing.....is highly problematic and completely misguided.
