Oh, i get it! It's funny because throwing any planet out of orbit can throw the entire solar system out of orbit, the planet will leave the range in which life is habitable, and all the ponies will die screaming in agony! I like it!
Shut it. That's not true. Everything has a reason to be on Earth and hating on a show that others like and telling them so much is just... Dumb. Keep the mean things that you say to yourself. And you should not think anything as lower lifeforms.
Oh you cute, naive little fucker. Nothing involving us has any real reason. We're entropy with a face, and the ponies perfectly embody our chaotic nature with their world that on the surface looks like an idyllic paradise (provided you have a high saccharine tolerance) but is in fact a grim hell of shit eating grins, torture, perversion, and badly made baked goods.
