Nah, Raibow Dash just tackles Griffin and pins him to the ground in such a way that their genitalia are in tight contact, which, given that they're both, well, naked, is very awkward. Griffin is however committing hyperbole by calling it "rape". The rest of the Noodle Incident is quite true, and made for a Broken Pedestal on his side (he was disappointed that Pinkie broke her promise to laugh at him, and that RD would initiate violence over insufficient information) and a terrible impression on theirs (he acted like a jerk throughout the episode; man's got issues).
For the past two months, I've been writing, and posting, roughly two thousand words a day of "Myou've Gotta be Kidding Me", a story set in a "My Little Pony: Friendship is Magic" fanfic universe, "Chess Game of the Gods". Outside of the sheer NaNoWriMo-like exercise of pushing out near-daily chapters, I've also been trying to keep in mind the various principles I've learned from Yudkowsky and LessWrong, and to try to present them in a way that people who like reading MLP fanfics might be able to appreciate.
I've just come to something of a minor climax with chapter 60, and while I'll definitely be continuing the story, this seems like a good time to mention it here, for whatever feedback and constructive criticism anyone cares to offer.
