1) Nope. When Equestria was founded by the new-found peace of pegasus, earth, and unicorn ponies it was a land without society. The only species that inhabited it were globally considered either animals or monsters in that they possessed no societarian structure.

2) Tried is a good word for it, considering the only reason America won was due to Britain being forced to focus completely on the French Revolution happening right next door.

No, the mere act and date of your country winning its freedom holds no real significance. It’s what the nation has done in the centuries following that mattered.

3) It was no coincidence. I moved to Ponyville on the day before the Summer Sun Celebration, because of the Summer Sun Celebration. That marked the end of my temporary position as an ambient musician in Canterlot. Everything had already been prearranged. I had no idea Twilight was moving here too, and neither did she, until after the Nightmare Moon incident.

4) That name sounds suspicious.

5) If this is a reference, I’m not following.

6) You’re a hateful creature for sending something like this.

7) Never heard of the genre. I’ve seen metafictional elements used time after time in other works, but never one dedicated to it.

Unless you count Mystery Science Theater 3000.
