The whole thing is a shitstorm, and while I say that I'm Pro-GG, it really doesnt have that much meaning. Its two completely different sites yelling at eachother, but having different conversations. One side is pushing for ethics in games journalism and fighting out the SJW clique that has taken over the games journalism, and the other side is screaming its a harassment campaign. If you visit any place that is Pro-GG, you will find out quickly that harassment is not tolerated. Pro-GG sites (outside of the mess that is 8chan's GGRevolt, which are a bunch of people that just start shit for no reason) tend to very quickly come down on people that are trying to harass others and flood reports, whether it be on Twitter, Reddit, or any other site.
The problem is that both sides can be pretty petty and handle things like little kids. I tend to just dislike Anti-GG because they always tend to be a certain type of person (typically males with crushing white guilt and a hate of nerds/geeks/gamers)
