Not the bit about evolution/homosexuality bit – as I understand it, Darwinian theory is a little bit more nuanced than that when addressing the ways that traits that affect the group/pack/tribe can be valuable for the species in general even when they’re personally evolutionary dead ends – but the suggestion that gamers and/or bloggers don’t have the opportunity to breed. I mean, speaking as a gamer… sure, back in the 1980s and 1990s there was a pretty lopsided gender ratio, but I know lots of female gamers these days. It’s been that way for a while: I’m trying (and failing) to remember the last campaign that I was in that didn’t have a minimum of two female players in it, or a female player and a female GM. Heck, my wife’s a GM herself.
Maybe we should update that particular cultural stereotype?
