This is the problem right here. No one, adult or otherwise, should have to endure the level of harassment some people have endured. It's easy to preach about thick skin, but when you have to endure constant verbal harassment, death threats, rape threats, people calling up your employer and coworker to tell them what a terrible person you are, people implying that they know where you live, etc. it's not that easy. I consider myself to have fairly thick skin, and I'm not going to be bothered by a singular moron calling me names on the internet, but I would not be able to endure that level of constant harassment.
And while I think the people doing these attacks are an extreme vocal minority, that doesn't really help the person being attacked by them.
So I don't begrudge the people who have left the industry over these attacks. I'm sad that they feel that is necessary, but never having been in their shoes I can't tell them their choice is the wrong one.
I'd say that it is absolutely their choice whether to leave or stay or react how they want I'd never take that from them.
However, consider what the person sending a rape threat/harassment wants? It's the same thing that's been true since middle school bullying, they want to know they've gotten to you, they want to get a reaction, the bigger reaction the better they feel. They want to hurt and know you've been hurt. It's been true from schoolyard bullies to people posting Mario appreciation threads on Sega boards to death threats to Akira Toriyama because Goku didn't show up this episode.
Trolls are *looking* for a negative reaction, there's entire subsections of trolling dedicated to getting people riled by any means necessary whether you believe or don't believe what you say.
So we've got a troll/harassment problem in gaming, worse, because it's the internet it's an anonymous troll problem. Calling out the harassment is fine, but due to the nature of anonymity it's (in my opinion) mostly ineffective because these people don't care about social censure against their fake twitter account or "budsmokah420" gaming tag. There's no personal investment to apply the censure to. It's a fire and forget missile.
This does happen in other mediums, actors/movie studios/critics get plenty of harassment, most of the time they seem to follow a "do not engage" policy.
The trouble is that you can't "stop" harassment in a world of free, anonymous, disposable accounts. There's just no vehicle to apply force to do so, they don't fear connection to their real life, nor to their disposable mask, and there will always be terrible people in every community. Think of it this way *the sort of person who would act on sending a rape threat to a woman in 2014 isn't going to be educated.*
So presumably the more effective idea is to reduce their megaphone, or reduce their inclination to act on their damage. In more mature commercial art mediums it gets mitigated because they feel it won't matter or change anything. Even North Korea's military threats don't get movies pulled from shelves, Budsmokah420 doesn't stand a chance.
Instead the modern gaming press is bent on *amplifying* their megaphone, retweeting their words, embedding them, broadcasting them, and making *everyone* react to them. To the harasser it's like they're the center of the universe all of a sudden. They're making people fight each other, angry words, people write articles, and even leave the industry. Suddenly everything anyone is talking about in gaming is because of the abusers, that's a huge power rush to a troll.
That's not going to make them stop harassing people, it'll make them harass more people and harass them harder because it's likely the most power they feel in whatever conditions their lives are in that generates such a person.
That's the idea at least, and from what I've seen it's a valid way to handle them. Personally I think it has way more of a chance of success then basically asking them sternly to stop when we can't *make* them stop.
If you're the sort of person who can't stand by, say something nice to the person being harassed, encourage and support them. That's another way to mitigate the harm done. We can't keep the arrow from leaving the quiver, in the end, that's just not possible so long as the internet is anonymous (and there will always be a way to be anonymous.) So the next best thing is providing good medical care.
