GamerGate, quickly

Unless you live under a rock, you're probably aware of GamerGate. If you're confused, here's a really simple version:

• The videogame journalism industry is by and large in bed with each other, and also in bed (sometimes literally) with the games production industry. People who support the GamerGate movement have a problem with this.
• According to people who oppose the GamerGate movement, GamerGaters are a bunch of sexists and racists (because a few of the targets of their ire happen to belong to "protected" classes, i.e., are not straight white males). 

That's it. That's the entire hashtag distilled into two points.
