I really don't care about being overlooked by the media, but sometimes the fact that I'm assumed to be male gets old. Not so much the "hey, I'm guessing you're male," but the gasps of "YOU'RE A GIRL??!!!?" That DOES get old, especially on FiMFiction. When you consider that lots of women and girls like ponies and always have, and that overall, cutting across fandoms, 80% of fanfic writers are female, FiMFiction is exactly where you'd expect female fans to be.
I've been to cons, but I've never, ever been to a meetup, because between my age and my gender, nobody would feel comfortable about my being there, and I don't want to be greeted with "ok, which doofus brought his mom?" So one reason female fans might be "invisible" is because no one knows what gender you are on the internet, and brony gatherings are mostly male, from what I can see.
This is actually a really adorkable romance plot in Bronies: the Musical, as it dawns on the very shyest brony, who could barely bring himself to go to a Brony meetup, that that cool dude he's been chatting with online, "Wild Horses," is actually a cute nerdy girl.
I think it's slowly getting around campus that "Professor X is a Brony, dude," and I have no idea what it does to my credibility, but if anything, I think it's gone up. ("Does she really have PONIES on her cellphone?" Yup.)
