Yeah, you’ve pretty much summed up the whole ridiculous “fake geek girl” fiasco. Some geeks got butthurt because some girls were supposedly “appropriating” geek culture, when they weren’t really geeks. That is, they weren’t being geeks the way that those geeks wanted them to be. And then other, more clearminded geeks spoke up to say “Uh, hey dummy, you’re not the one who gets to decide how people enjoy the things they want to enjoy”.
Edit: John Scalzi was right in the thick of that who controvesy… His post on it is here (entitled “Who Gets To Be a Geek? Anyone Who Wants To Be”)
