You may be surprised to hear that some of the most attractive, fit, funny people I’ve ever met worked at Marvel Comics. The first time I took a friend to my office, she whispered to me, “Why is everyone here so hot?”
The problem with comic art isn't the fact that women don’t look like that in real life. The problem is that artists' idea of a stylized fantasy woman is "put all the naughty bits on the front so we can see them at the same time."
Your stereotypical nerd is usually white, male, teenaged, disheveled and frumpy. Race and gender diversity hasn’t generally been a strong point in fandom. But that hasn't stopped me from going to "the con."
