Women who like "masculine" things are mocked and jeered at, accused of not being "real" fans and of being "attention whores" (or, sometimes, just "whores").
Men who like "feminine" things are given a documentary praising them for their "progressive" views and feel such a large amount of self-importance that they claim they're "oppressed" by women who are (often rightfully) scared of them.
I've never seen a more misogynistic, homophobic, transphobic, and violent fandom than the one grown men have created around a show about multicoloured horses. There have been several times when I've been sexually harassed by self-professed bronies (all of them were over the age of eighteen when I am clearly a minor), who then have the nerve to say that people (especially young women) are being "sexist" for fearing them or for feeling uncomfortable because of their presence.
I'm all for breaking down gender roles, but bronies are definitely not doing that properly (if at all). Bronies: you are not oppressed. You are not progressive. You're assholes. You're -- as the title says -- entitled pricks.
(Also, not every MLP fan is a brony, and yes, I know that not all bronies are like that.)
