What's happening here is the standard (especially in GG) circle-j where GamerGaters theorize that something is a "false flag", then someone digs out some minor coincidence, KIA has a field day and declares that the case has been proven, and nobody there revisits the issue, usually genuinely shocked that anyone would disagree.
I'm _still_ arguing with people who think (or claim to think) that Nathan Grayson wrote anything at all as a result of his fling with "LW1" [the GamerGate term for their primary target, who isn't a journalist FWIW. The women herself has suffered enough harassment, so I'll subvert this term to actually avoid mentioning her by name respecting her wish she be kept out of it.] They read Grayson did, they've only listened to people who said he did, as far as they're concerned it's true, and no amount of "OK, point me at the articles he supposedly wrote" will change that. Given this is the original attempt to redefine GamerGate as an "ethics" campaign, something even this story has fallen for, that's a pretty bad thing.
1. Eron Gjoni initially tried to post his revenge-ex "tell all" about "LW1", to the forums of Something Awful. SA deleted it immediately and banned Gjoni.
2. Gjoni shops around, finally finding 4chan tolerates it long enough to stir up support from various anti-women trolls (well, it's 4chan, of course they're trolls.) Yadayadayada Adam Baldwin yadayadayadayada front page of New York Times, article about GamerGate's harassment and death threat campaign.
3. Goons (SA's term for forum members) discussing the trainwreck on Something Awful's forums notice the New York Times is covering a controversy that started at... Something Awful and post words to the effect of "What started here ended up on the NYT!"
So what happened then? Well, GamerGate developed a consensus, immediately, without any evidence whatsoever beyond forgetting, somehow, that SA was where Gjoni started trying to destroy "LW1", that Something Awful was behind all the death threats and was making them to make GamerGate look bad.
Because that totally makes sense. One, out of context, forum comment, with no actual quotes from SA members organizing this shadow campaign.
I mention this because it's one case where you specifically see the mindset. Something is "proven" because it gets repeated within KIA enough that it becomes an unquestioned fact. This is how GG holds on to its useful idiots long enough for them to make idiots of themselves.
