A hypothesis: Gamergate is more powerful than we are.
An elaboration: we all know that gamergate, despite what its followers might intend or even believe, is essentially a (sometimes violent) defence of the status quo. It is those most privileged in games culture (young men who like particular kinds of empowering games) defending the top of their hill against those more diverse kinds of games creators and critics who dare attack their privilege. They are seeing the games they like go from being about 90% of all videogames down to about, oh I dont know, 75% (at best). And that feels like a real attack on them! So they are defending the status quo. Now, if they are defending the status quo, then that suggests that they are the ones with more power and that we (those more in favour of diverse and progressive games cultures that isnt afraid of criticism or indie games or walking sims or twine or whatever) are the margins trying to effect change and make space for more people. Thats what weve been doing for ages, I guess, but now weve squeezed the pimple of game culture to its pussy head and its not very happy about this.
So gamergate then are the ones with all the power because they are the status quo. That is not to say they are majority, but I think posts like this one that point out just what a minority they are run the risk of being like those kind of posts that point out white people are a minority in America now: quantity isnt everything. Gamers have been the underwhelming minority of videogame players for a long time, and they are only becoming less and less significant to broader play cultures. This is totally true. But they still hold a lot of the power, because thats where the power has always been, especially through the 80s and 90s as the gamer identity was cultivated by games journalism and marketing as Ive already discussed. So just as white people still hold the vast majority of the power in Western countries that may now have more non-white citizens than white citizens, the core homogenous gamer culture still holds a whole heap of the power in games, even if most videogame players are not gamers. They are the ones AAA publishers care about. They are the ones most core games journalism outlets cater to.
This is why I dont think silence is necessarily going to achieve anything, because the silence of the marginalised is what the status quo depends on to keep its power. Thats kind of how it works.
