I mean, she complains that there's no black ponies, but the only reason she thinks there's no black ponies is because none of the ponies have any identifiable racial characteristics, and to her, white = normal. She'd respond that it's not her equating whiteness with normality, she's just pointing out that the racists running the show equate whiteness with normality. But she has no evidence for that.
She already knows that the show is made by a bunch of racist sexist homophobic chauvinist men, so she looks for a racist sexist homophobic chauvinist interpretation of everything she sees in it, and then acts shocked at all the racism, sexism, homophobia, and chauvinism that she sees, which then serves as more evidence in her head that all media is made by racist sexist homophobic chauvinist men. All of which serves only to undermine serious efforts at rectifying racism, sexism, homophobia, and chauvinism.
If she had actually watched the show rather than just looking at a picture of it, she'd see that it's by far the least sexist show ever made for girls. And it was made by a woman.
And anyway, there's a black pony in episode 9.
