I enjoy Steven universe. CLEARLY I AM A SEXUAL DEVIANT BY PROXY.
Him being a 'brony' is irrelevant. As much as I am utterly exasperated by the idea that male fans of mlp needed to grant themselves a special 'status' to justify their existence as a fan of the show instead of ..y'know just being a fan of the show. It really doesn't have any baring on their personality and humanity.
I quite like the MLP cartoon also, it's a solid show for people that can easily keep parents and older people entertained. It's a family show. Not a 'kids show', so can be enjoyed by anyone.
This guy is cleary a bit of scum sucker, but only for the reason that he's sexually targeting underage girls. Not for his choice in programs.
In early days the male fans of the show 'My little pony: FiM' got self concious about the fact that they enjoyed it un-ironically so they needed to declare themselves 'super special' fans, as opposed to regular fans, thus the term 'brony' came about from a joke made on 4chan. Now it just serves to piss most people off when you call them one. It's a minor derogatory for someone who usually wears or owns a piece of MLP merch like this guy.
