No, Glenn Greenwald, GamerGate did not invent the term Social Justice Warrior. We are helping to popularize it though. And no, it means far more than merely "politically correct".

Actually, I would define an SJW like this:

Age: Typically twenty-something. It is rare to spot an SJW in their thirties because exposure to the real world is typically fatal to the SJW mentality. However, if a middle-aged SJW is spotted you can be certain that they are either trust fund recipients or occupy a job that requires zero results or accountability, like a tech writer or an adjunct professor at a community college.

Appearance: Obnoxious hipster glasses perched on the edge of their noses while they look down smugly at the Retina screen of their $3000 MacBook Pro. A self-satisfied smile will grow across their lips (Gawker made a joke about those pathetic people who live in flyover country!) as they slowly take a sip from their container of fair-wage 100% organically grown coffee. But the smile suddenly vanishes as the sickening taste of real milk passes over their lips. They had commanded the barista to use vanilla soy-milk in their coffee, not this "real" stuff which, let's face it, is only for babies and hicks. Their hands tremble in anger as they scowl at the offending barista. Then, slowly but surely, they begin to type out a devastating Yelp review. Yes, the world must hear about this latest outrage!

Gender: Trick question, gender is a 100% social construct. Consult Tumbler for the latest acceptable pronouns.

Politics: Here is the crux of the matter. To the SJW, everything is political. From a scientist's shirt to the amount of pixels used to render the cleavage of a video game heroine, literally nothing is what it appears to be. Instead, a dark and subtle fabric of oppression has been woven behind the scenes. And it is this unseen reality that must be exposed at all costs by the SJW. It is a rare thing, to be able to pierce the veil of this oppression and privilege. Fortunately, the SJW, nay the lightbringer, is able to do just that. And all they ask in return is that everyone conform to their whims about what is and is not acceptable. Truly, the unwashed masses who claim to just want to go on with their lives, to read what they want to read, to watch whatever TV shows they like to watch, to use the words they want to use and to play the video games they enjoy playing, are ingrates and ignoramuses.

We are unworthy of the light the SJWs bring into our dark and inconsequential lives.
