8. Males are useless

Well, not useless. They're useful for pulling plows, moving big things, and pulling carriages. In the feminist paradise of Equestria, mares travel in carriages pulled by stallions. You sometimes see males in the background, standing around in fields staring at nothing, waiting for a chance to be useful to some female. The Equestrian royal court is full of stallions standing around in armor and flexing their withers, although whenever there's an actual military threat Celestia leaves the boys at home and sends a cadre of untrained adolescent mares to deal with it.

In a show about friendship, not a single named character has a single male friend, unless you count Twilight's "friendship" with Spike (see slavery below).  But there are male characters. There's King Sombra, a personification of evil. There are Flim and Flam, who try to take the Apple family's farm. And there's Discord, another personification of evil.

Not all males are evil.  There's also Snips and Snails, who are morons; Snowflake (also a moron); Shining Armor (prince of surfer dudes and donsel in distress); Blueblood (a cad and a moron); and the Diamond Dogs (morons with bad breath).

There are positive male role models, too. There's Big Macintosh, who pulls heavy things all day for Applejack, doesn't try to think, and limits his speech to "yup" and "nope" as males should. There's Mr. Cake, whose sole object in life is to avoid upsetting Mrs. Cake. And there's these guys:

Featherweight and Pipsqueak are the perfect males: They don’t say much, and they’re small enough to step on if they get out of line. The message for little girls is that males may seem cute and harmless when they're little, but unless properly disciplined, they'll grow up to be evil and stupid.

7. Ponies are control freaks

In the land of Equestria, ponies raise and lower the sun and the moon, herd rainclouds and schedule storms, tell the plants to grow, feed the animals, shake the leaves from the tree when  they want them to fall, and decide when winter will come and go.

All those things used to take care of themselves. There's one place in Equestria where they still do—the Everfree Forest. It's seen as a place of evil and nightmares. The words "everfree" strike terror into the hearts of ponies, just as they did into the heart of this man:

Not as controlling as Princess Celestia.

6. Ponies are imperialists

In "The Crystal Empire", said empire appears magically, temporarily freed from the despotic rule of King Sombra (a male, 'nuff said). The Equestrians send a crack force of adolescent mares to prevent Sombra's return, to—free them? No; to place one of their own spare princesses on the throne and add the Crystal Empire to their dominion.

5. Ponies are racist slavers

Fluttershy keeps chickens in a coop and eats their eggs. In "Applebuck Season" we see that ponies herd, rope, and milk cows even though they're intelligent enough to speak. Perhaps more disturbing is how Twilight pretends to be a mother or sister to the baby dragon Spike. Spike was stolen from his true parents as an egg (probably by Celestia), given to Twilight to experiment on when she was just a little filly, and when against all odds he survived, she made him do all her scut-work from then on without pay and sleep in a basket on the floor.

4. Fluttershy kills some animal friends to feed to other animal friends

In "One Bad Apple" we see Fluttershy, kind, gentle, friend to all animals, making friends with fish. In "Dragonshy" we see her killing those fish to feed them to ferrets, without even asking whether the ferrets are hungry. This isn't kindness; it's obsession. Now we just need an episode where she throws baby birds out of the nest so she can tend to their broken wings.

3. Princess Celestia sends anyone who doesn't obey her to some kind of hell for a thousand years

In the first episode, we learn that Princess Celestia, benevolent ruler of Equestria, had a little sister who refused to obey her. So Celestia exiled her to the gray, dusty, airless, silent surface of the moon for a thousand years. And never wrote.

In season two we meet Discord, a being of supreme evil whom Celestia turned to a statue in her garden for a thousand years for not doing what she said. On actually encountering the guy, we discover that he's basically—a guy (see males). He doesn't do anything very dastardly; he just thinks Celestia's perfectly-ordered world is boring (see control freaks above). When he talks to her, he takes the high moral ground: "It's quite lonely being encased in stone. But you wouldn't know that, would you. Because I don't turn ponies into stone!" But there's a happy ending: He ends up encased in stone again. The really creepy thing about this episode, though, is that Celestia's sculpture garden where Discord is imprisoned as a statue is full of other statues.

Her cousin Jadis arranges hers more tastefully.

“But Celestia had no choice! She had to sent Luna to the moon. (And never write.) She had to turn Discord into a statue.”

In reply, I have compiled this list of characters who have defied Celestia and not suffered a thousand years of torment:

(nopony)

One out of many is a tragedy. Two out of two is a policy.

2. Hell actually exists in Equestria

In "It's About Time", Twilight Sparkle encounters Cerberus, the three-headed dog, and worries that this means the damned (who presumably once disobeyed Celestia) may be escaping from the underworld. The actual lines from the show:

Twilight Sparkle: That's Cerberus! He's supposed to be guarding the gates of Tartarus, but if he's here, then all of the evil creatures that have been imprisoned there could escape and destroy Equestria!

Spike: Destroy Equestria?!

Twilight Sparkle: Yeah, isn't it great?

1. Twilight Sparkle murders a room full of innocent ponies

In the episode "Too Many Pinkie Pies", Pinkie uses the magic Mirror Pool to make copies of herself, so that she can attend all the different events that her friends are having at the same time. This multitude of pinkies proves supremely annoying. Instead of exporting Pinkies to towns that don't have any and creating a profitable party-catering franchise, Twilight solves the problem by getting them all together in one room, then murdering all but one of them by blasting them with magical energy from her horn.

But it's all in good fun! See how much fun they're having as they watch their fellow clones being killed off one by one?

“Look, even her blood is pink!”

So people shouldn’t worry that we’re gay pedophiles because we’re bronies. They should worry that we might murder them, sell them to Somali slavers, or vote for Hillary Clinton.
