Holy fuck, I tried to read the Wikipedia article on Gamergate because all I really know about it is Feminazis vs. Misogynazis, but my eyes kept glazing over. Can someone TLDR this controversy for me please?
Sure!
Guys who were picked on in school, and could never figure out why the girls they liked would never go for "nice guys" like them have grown older. Now they've made enough money that a good portion of modern media is now focused on them and trying to vie for their consumer dollars by producing media which appeals to their interest in comics-movies, fantasy TV shows, science fiction TV shows, and related video games. It has currently become the dominant paradigm of popular media.
Because this type of media has become "normal," most everyone is enjoying it, which means it's no longer the private club house of picked-on guys who can't get girls. Now open to more serious scrutiny, they've experienced an influx of people who are suddenly questioning why fantasy women have to wear chain mail bikinis, why women superheroes always point their ass at the viewer on comic book covers, and why female gamers are required to play their opposite gender in video games.
TL;DR - A large percentage of geeks fear change, even though having more people interested in their bullshit hobbies would improve their odds of overcoming their #foreveralone status.
Ah, sorry, forgot an important side-note: These "nice guys" who couldn't get girls are now choosing to make their point about how they've been wronged by stalking, hacking, releasing personal address and phone information online, threatening rape, murder, and calling in bomb threats.
