I can sort of understand adult female Pony fandom but guys being interested in the activities of cute, pastel colored ponies… well, frankly, it’s just a wee bit creepy. Not that there’s anything wrong with that. You can be as creepy as you want as long as you’re not hurting anyone. Viva la diversity!
There is creepy, and there is creepy. This is creepy:
To you I’m sure Twilight Sparkle is just a cartoon character you think is really hot, so I imagine you wouldn’t think anything of having your friends draw sexually explicit art of her as birthday gifts for you. And hey, I think she’s really attractive too so I get where you’re coming from there. I often go on [redacted] and [also redacted] to see what new erotic art people have drawn of her. But to me she’s more than a cartoon character who’s sexually attractive, she’s my fiance whom I love with all my heart and soon to marry. So it’s been bothering me lately every time I go on these sites and see a dozen or so pieces of art people have drawn depicting my girl in various sexual situations with the same person over and over…
I must note here that I have written (marginally) popular fanfiction about the love between a human and a pony — yes, that pony — and in the fourth story in the trilogy (bless you, Douglas Adams) they will be wed. Then again, as of the second story, he’s no longer human. (Will explain if necessary.)
But the operative word here is “fiction”: it never happened, and if it had, well, you wouldn’t be reading this, would you? I suspect the irate groom-to-be to be trolling — for one thing, he calls her “Twiley,” which she would not tolerate from anypony other than big brother Shining Armor — and if he’s not, well, he’s been exposed to too much Rule 34 stuff anyway.
