That means I still have no clue what gamergate is.
I don't purport to be an expert on the subject, but from what I've seen over all this time is...
It all started when an ex-boyfriend of an indie developer revealed that the dev had been sleeping with people from some gaming website. (You can tell how much I care about the drama-filled aspect given how I remember the exact names.

) One of these people had written articles and stuff about the developer's game (Depression Quest), but there was nary a mention of this sordid affair! (dun! dun! dun!)
This is where the two schisms of GamerGate occurred. I'll see if I can separate the two out:
1) People were mad that the relationship was not disclosed as it could represent a conflict in interest. This prompted a sort of witch hunt on unethical journalistic behavior. Some websites that lacked any visible code of ethics would go on to publish them on their website to help ensure readers that the site takes its credibility seriously. There have been quite a few other instances of unethical behavior or possibly problematic relationships that have been revealed since then. The most recent that I saw was some Ubisoft employee and a guy at PC Gamer. Said guy had written articles about Assassin's Creed: Unity.
2) As is unfortunately common on the Internet, some people decided to be less than savory about the developers affair and give her crap... lots of it. This included the usual death threats, rape threats, etc. A lot of this sparked an outcry from other females either in the industry or outside of it (like Anita Sarkeesian). Well, as you can guess, the hatemongers didn't let them go unscathed either, and all that ended up doing was adding more fuel to the fire. It didn't help that
multiple news sites were posting reports that "Gamers were dead" (even venerable sites like ArsTechnica). Now, even those that had nothing to do with the terrible remarks were being lumped in as misogynistic, and they were not happy.
So, in short, it all started as a crusade against unethical conduct in gaming journalism, but a separate issue
very quickly spun off about misogyny and the poor representation of women in gaming. The biggest issue about the schism is that no one cares about the former because it isn't nearly as polarizing and is too specific of a topic. I don't think I've seen any talk of the lack of ethics (real or proposed) in the national news, but they've definitely talked about the treatment of women on the news.
