Being "left-leaning" or "liberal" doesn't proof anyone against misogyny or pettiness, and I don't see any good "left-leaning" reason to believe the "SJW" even exists as an actual category that could be applied to any of GamerGate's targets*. The harassment of whom hasn't stopped to this day, by the way, because it started out as the point from the beginning and has remained the point to the bitter end. The chatlogs showing 4chan's planning of #NotYourShield as a distraction have been public for a long time; anyone who participated in that, or any other aspect of GamerGate, under the impression of supporting something "sincere" was duped. Those are just statements of facts in the public record.
This is particularly ballsy of you, I think:
Shaka Zulu said:
If they really want to see inclusion, they have to start telling their brethren (and others of color/women) to get into the industry and start making games,
... because you have to know that Brianna Wu and Zoe Quinn were and are targeted by screeching mobs of hateful fanboys for doing precisely this. All the robotic repetition of "it's about ethics in game journalism" was only ever a smokescreen. The targets of GamerGate were small indie creators who started getting attention for their games and happened to have vaginas, or commentators and critics who had the audacity to be young and female and exhibit any kind of propensity for non-right-wing critique.
(* If Anita Sarkeesian supposedly qualifies as an "SJW" for calling out sexism in games in ways poor thunderf00t can't cope with, or Zoe Quinn supposedly qualifies for calling out the Fine Young Capitalists for transphobia, then it fails as an analytic category and it's time to go back to learning some basics about how criticism and debate work.)
