When women say "allowed to do x," they typically mean "celebrated doing x," because they've never been told "no" with any sort of regularity.

Yeah, I have the same doubts. Whatever else geekdom is or isn’t, it’s never been a subculture that was running low on fat girls. I get so bored of every other Internet wannabe-hero portraying ordinary behavior in their subculture as somehow pissing in the face of all the people “who told me I can’t.” Who told you, and what did they actually say? It’s always very non-specific. But shit, I’m in law school and all the minority women (and white women too) post endless wank about how “they” told me I couldn’t be a lawyer but I showed “them!!!!” I guess as long as you’re not a straight white gender-confident male, there is a lot of online YAS KWEEN clout to be gained by lying about how brave you are for taking a selfie.
