I guess that "gamers" perceive women are a sort of living symbol to alienated and lonely men that represent an antidote to that alienation. Perhaps it comes from this idea that women are more likely to be sociable, lively, and engaged in the world that for such gregarious and amicable people to be using social anesthetics like video games is kind of an oddity.

It's like the Virgil/Matt debate about video games meta narrative. Video games are a social anesthesia and waking hallucination, but the underlying context is the abuse to over indulge are symptoms of a problem within capitalism where identity is cultivated and sense of worth into the commodity and experience. And when you dream, and you see a weird object or event, you begin to start waking up. A woman interacting in video games isn't really a strange thing for several years now, but it can still be uncommon to fully appreciate.

Or it could just be like a boys only club thing, dudebros being dudebros.
