I honestly don't think that a lack of social skills is to blame. I'm not the most social creature and that sort of behaviour horrifies me.
I think it is more likely a lack of empathy, combined with the view that the internet is somehow not the "real world" and an entitlement complex of incomprehensible size.
Perhaps we define social skills differently... or it's just the wrong word (probably).
But I do think a lot of the aggression towards women stem from insecurity and lack of ability to comfortably converse with opposite gender. Those in my mind are social skills.
I would agree that the symptomatic cause of the current situation is insecurity, but not about "talking to girls". It's fear of losing what you consider to be yours. Whether or not you have any sort of right to it--and I think it is very safe to say that, no, young white males do not have an inherent right to be catered to by all aspects of the game market--doesn't matter, you think it's yours and they're taking it and that means it's OK to call the cops and get a SWAT team sent to somebody's house. (Apparently.)
The fear that the universe is zero-sum is the major way that regressive elements maintain societal control. The rich guy takes nine cookies, elbows the middle-class guy, and says "hey, the poor guy's gonna steal your cookie!", and the middle-class guy hops to. It applies here just the same--if you're so unable to get outside of your head to entertain the idea that maybe games not targeted directly at you could maybe, just maybe, expand your horizons a bit and make your life better, while making life better for other people...well, you freak out, and apparently you don't stop freaking out.
Personally, as a straight white dude, I am marvelously unthreatened by the idea that people make games for people who aren't me. I encourage it. But then, I have the basic reading comprehension to not try to say with a straight face that "gamers are dead" was a pejorative rather than market analysis, so I was probably never in the wheelhouse for the hatemongering.
