I really don't think this has anything to do with feminism. I'm hardly plugged into this whole weird online subculture around gaming, but it's clear that there are now camps pitted against each other and engaged in tit-for-tat. The actual issues? Long gone by the wayside.
And the so-called "SJW" side, well, they are hardly blameless. I personally found a lot of these people to be quite vitriolic and accusatory and derogatory of others. I noticed this when I started visiting neogaf more and got linked to a lot of games journalism and the whole subculture. Some of these people seemed quite strident and intent on creating an enemy and often being quite divisive. Well it appears they now have an enemy.
This is really what the whole Zoe Quinn thing is to my mind. An opportunity to hoist one of these types by their own petard, so to speak, as a kind of pushback, and then an attempt by others to squash the whole thing, which of course only made it worse.
It's bizarrely entertaining and more than a little ridiculous, but as this incident shows, shit can get quite real.
