I'm Russian, And I hope that you're happy with yourself, you have proved your grammar skills on the background of my bad English. Good job.
Now about Sombra, Nightmare moon, Chrysalis and Cerberus (yeah I know that Cerberus should guard the gates of Hades, not Tartarus, here the writers made a mistake) This villains is a part of MLP universe (except Cerberus, but I can't call him "darkspawn" It's just a big cute dog with 3 heads), So these villains is a part of MLP universe, therefore, they are entitled to be in this cartoon, they it is a vital part of the plot.

Finally somaone understood me! Yes, it's exactly what I tryed to say. Thank you.
I must admit I too overreacted. I don't know what came over me yesterday, now I find it easier. I apologize for my emotions.
