Bronies are still relatively new, but the brony fandom has far more attention than the furry fandom because it's based around a particular popular show with a corporate backing(Hasbro) rather than just a genre of art(humanoid animals). So there you go. But furries I think still remain in that "last place" of the fandoms when it comes to receiving abuse.
Long ago it was the comic nerds, then the trekkies, then the Star Wars freaks, and so on.

Hell, I remember when liking anime meant you were a pedophile.
