Actually I'm pretty sure that SJW's are puritans in disguise at this point.
Actually, I'm pretty sure that comments like that make my point. SJW is just another de-humanized group for people to project their personal devils onto.
Every time something comes along, the first thing they start screaming about is "sexism" or "muhsoggyknees." Strange that it just keeps happening over and over again, you know like with Matt Taylors shirt(who was made by a women).
Most of us are made by a woman, but I'll assume you mean the shirt. The people who are upset about this, and it doesn't seem like there's that many of them (your mention of this was the first time, I'd heard of it), are more upset that he wore it to a major press event and that no one thought to say, "Hey, before going on international television, maybe you'd like to change into something more appropriate?" To them, at least, this is indicative of a casual sexism endemic to the sciences and science reporting, where female scientists are judged by the appearance and male scientists by their accomplishments. The fact the shirt was made by a woman wouldn't actually matter to them and would appear to be disingenuous deflection because it's not the shirt, it's the where and the why it was worn that matters to the critics.
I'm sure though that you'll also find that the majority of people in gamergate are left-libertarians. And the majority of anti-gg are left-authoritarians.
I would suspect that you're suffering from the false-consensus effect and projecting your beliefs onto other people in Gamergate, possibly also the halo effect with respect to the people who don't like Gamergate. Of course, if you are correct about Gamergate having a libertarian base, then everyone else would be relatively more authoritarian, virtually by definition since just about the only group less authoritarian than libertarians are anarchists.
Additionally, when I spent some time looking over the posts on the Gamergate hash tag, I noticed several references to culture war against the left, and in particular how offline conservatives should follow Gamergate's tactics (against Gawker and Kotaku) to deny left leaning publications advertisers, which is certainly not what I would expect from a mostly left leaning group that advocates against corruption in journalism. For that matter, why do some of these supposed libertarians think that censorship of views they dislike is a valid solution to "corruption"?
Beyond that, I wasn't actually talking about Gamergate itself, which is a somewhat random assortment of people who all happen to be outraged about vaguely similar things and have twitter accounts, but more specifically about the people who use SJW as a pejorative epithet (which may or may not significantly overlap the people in Gamergate). Of course, on the other hand, I'd never heard of the SJWs until a bunch raging Gamergaters start spewing it all over Slashdot, so there is that.
