So there's this thing, wherein certain domains of fandom are considered to be male-only clubs and female geeks are questioned and harassed and ridiculed and told they can't possibly like what they like and challenged to 'prove' their fandom because obviously people with breasts are incapable of properly liking science fiction. Or something.
Anyway, this video response to that phenomenon is fantastic. Many of my favorite people show up in it. You should watch it.
