So, people are really going to take A SINGLE SERIES of tweets at face value? Sorry, this looks like someone trying to join the bandwagon, to me. This outrage culture is out-of-hand. People {"The Victim") abusing other people {"The Public") to abuse other people ("The Accused").
If he feels strongly about this, then he should get with one the the organizations that fight harassment in the workplace, and file a lawsuit. He's accusing people of wrongdoing and is using the public's outrage to get back at the accused with nothing more than his word against theirs. This doesn't make him an innocent in my eyes.
The first thing I want to touch on is your use of the term "outrage culture." This is a term mostly used to delegitimize things people have reason to be upset about. "Outrage culture," like the prejorative "SJW", is a gutter term that targets anyone who challenges the status quo. In your case, you are using it to delegitimize a potential harassment victim. People do get disproportionately upset for stupid reasons: the ending of Mass Effect 3, for example. But do you really believe that people who come to the aid of a potential victim of a sex crime are part of a manufactured "outrage culture"?
I will give you the benefit of the doubt and assume you don't believe that.
The second thing is that coming forward when you are a harassment victim requires a great deal of support because people like you are always swift to deny their claims. Somebody coming forward in an instance like this is asking for help, or is trying to protect others, and by not believing them you are telling them they shouldn't have spoken out. You're telling them it was a mistake to stand up for themselves. You're telling them to go back where they came from because they didn't ask for help the right way.
People are supportive of people who claim to be victims of crimes because you should not assume people asking for help are lying. This is morally repugnant.
Nobody is asking for ND or Sony to do anything unreasonable. People are asking for, and waiting for, a statement. That is how these kinds of situations actually work. Somebody makes a claim and then people wait for the response. But when somebody is the potential victim of a sex crime, you do not tell them to wait until somebody has spoken on behalf of their potential abuser. You offer them your support and you wait and see what happens.
I want you to imagine you are robbed at knifepoint. They steal your money, cell phone, and keys and leave you with nowhere to go and no one to call. They also slash you in the face, leaving you bleeding.
Desperately, you go to a shopkeeper and tell them your story. Instead of inviting you in and calling the police for you, they are skeptical. They say you're probably making it up, but even if you're not, they can't be sure so they aren't going to help you.
So you go to the closest house and knock on the door. You ask for help and they say you don't seem trustworthy. You point to your face and they say it could be self inflicted. Maybe you're trying to get in the news. They are mad at you for even coming to them.
So you go to the police station. There the police ask you what happened and challenge you every step of the way. They ask why you didn't turn and run. They ask why you didn't take a cab home if you knew you had to walk home alone. They ask why you didn't come to them first if it was so serious. They tell you that they're not going to help you because you should have known better.
This is how it usually feels for victims of sexual harassment and abuse.
The absolute least you can do is listen to them.
