Scary to think that the venn diagram of young gamers and future programmers is pretty substantial. The ratio of men/women in college was pretty abysmal. This may not be the exact cause, but it certainly doesn't help the cause. Truly is a shame that so much talent is driven to other fields due to lack of basic social skills.
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.
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.
