Hmm, I've got to disagree with you on the Derpy thing- I'm not in the fandom so I didn't petition them or anything, but I'm really glad they changed it. One of my best friends has cerebral palsy and kids used to bully her by calling her derpy, so I was really shocked a show about tolerance would call a pony that in the first place. :/

I totally agree with you on the Disney thing, though! It's such a fad to be all ~dark and intelligent~ pointing stuff out, when all they're really doing is ignoring a good three-quarters of the movie's actual canon. So obnoxious.
