A cautionary tale. This Buzzfeed video about "If Geek Girls Acted Like Geek Guys" may be more instructional than outright funny, but it's definitely worth watching to see the hassle that some nerdy men needlessly put nerdy women through in reverse.
The real tragedy is that condescension is a better treatment than outright scorn, which is also far too common a response when women enter nerdy places like comic shops. I've said it before and I've said it again: If you've ever once felt ostracized or looked down upon for your nerdy passions or hobbies, you have the moral imperative to be as accepting and supportive of other nerds — all other nerds — as you can. Because you know. And knowing is, of course, half the battle. The other half? Don't be an asshole.
