I do. I'm proud to have been a brony for four years!
While I was as gratified at the message of the episode as anyone else, I think it's a mistake to try to drag the show into the political debate. Since the cast and crew are doubtless hardcore liberals (hey, they're entertainers, and Canadians!), too much touting of the episode by conservatives could lead them to react by going in the other direction.
The Ponies should be like Mount Vernon in the Civil War: neutral ground. Let's all leave it at that.
I am a bit afraid of that.
I know that Ashleigh Ball (Rainbow Dash and Applejack) is a whacko, after she tweeted a (fan) drawing of Rainbow and Applejack getting married.
I can only hope the producers smacked her around a bit for that one.
