Honestly I find the brony thing weird and I usually don't care what people like and don't like we all have opinions but I mean come on you are a grown man and you watch a show made for little girls. I feel sorry for the creator I mean guys have sexual fantasies about ponies that they created God i would feel so violated that my art is jerk off material for some neck beard. But back to the question I would ask him why he likes it and try to get into the head of a brony. Also try to get him into other things other than ponies
