Jay Allen presents a unified theory of internet assholes (essentially what I was grasping towards, but failed to reach, at the end of my TechCrunch article on neoreaction):
They want you to lift the veil pulled over your eyes by the progressives who secretly control society. Like Neo escaping the Matrix, your choice is to wake up and see how the world really is, discarding religion, subjectivity, and feminist indoctrination. Conspiracy theorists, Men’s Rights Activists, Pick-Up Artists, GamerGate, even the Neoreaction: all of these communities share a common creed, tech-fluent and superficially self-aware. To outsiders, it’s distinctly conservative. But they don’t see themselves as conservatives at all.
Welcome to the Red Pill worldview, where the entire world is a game and the people who are winning are the best players.
Another interesting phenomenon is the way these different but overlapping movements are trying to hijack, or at least capitalize upon, each other. For example, MRA guy Roosh Valizadeh starting a GamerGate themed website called Reaxxion.
