So, if I understand this correctly: A musician, struggling to garner attention, isolates himself from a mainstream audience by attaching himself to My Little Pony. Then causes trouble in the extremely niche fandom he's pigeon-holed himself in.
I'm guessing his Brony stuff isn't connected to his real name, and that he teaches guitar or something for a living. He is 40, though. Maybe he's gone through so many avenues already, Brony music is the only place left.
(And honestly, I somehow feel like identifying himself as a Brony isn't a move that attracts the high-brow music connoisseurs he wants).
