She also openly admitted throughthesetweets that she detests the My Little Pony Equestria Girls dolls – though she has not said anything one way or the other about the movies themselves. Furthermore, this interview details that she would have quit if Hasbro approached her with the idea if she hasn't done so sooner.
She has decidedly mixed feelings about Twilight Sparkle's promotion to royalty at the end of Season 3. While she did intend for Twilight to be Celestia's successor (which as of the fifth season has not happened), she also said, "I never used the words 'Alicorn' or 'Princess'." She also complained that the show-accurate Funko figurine line did not have a wingless Twilight, lamenting that her set would remain incomplete as a result.
Lauren admittedly wishes she didn't write the episode "Equal Fights" from The Powerpuff Girls. In retrospect, she finds Straw Feminism too touchy a subject to discuss in a cartoon so lighthearted.
She doesn't like Straw Feminism in general (keyword there is "straw"). As a staunch Second-Wave Feminist who has faced discrimination in her professional life, she has expressed displeasure at the excesses of Third-Wave Feminists when they act exclusionary. This is one of the big reasons she gave a full-throated defense of the Bronies when prominent Feminist publications decided to attack the Periphery Demographic.
Lauren's response to knowing someone knows about Supermodels Don't Know Kung Fu, a very early comic she made, qualifies as well.
She was also very excited at getting John de Lancie, a.k.a. Q as Discord in the second season, stating that she's a big Trekkie and loves Q. Incidentally, she created Discord immediately after going on a two-day ST:TNG binge.
