While I'm not a fan of satyr (coincidently Satyr & faun are half goat half human) being the result of human/pony breeding, I think it is a reasonable addition to the fannon. It's a shame some people don't think so.
The fact that bronies are so against this just defeats the purpose of being one. Maybe it's because I'm not bothered by things unless some one is clearing getting hurt, but i think these things are pretty cute. As i have always said to MLP haters, if you don't like something, don't make such a big deal outta it, it's not going to go away. this is the same thing that happened to Twilight becoming and alicorn, and the Equestria Girls movie, which i plan to see.
