No, you are actually sane and redpilled.
Writers ruined the magic and presented us the world, where friendship IS actually power, not magic. When Cozy was placed in Tartarus - people were angry and questioned if it's a good thing to place a mentaly unstable child in literal hell. Then the leak happened, people are beyond pissed and it's going to be worse during the official airing. This is not the show we love, this is some gruesome turd shat by Haber.
We're at the point where we start thinking if Equestria is better than our world. 9 years of love and tolerance was a huge, fat lie. Alicorns crave power and they wrap it with fancy words, like "friendship, tolerance". Cozy wanted to achieve this power the same way, as Celestia and Luna, but she was unexperienced, too young to reach the bullshit 4d chess levels of these alicorn cunts. Poor girl paid the highest price for not being as manipulative as Celestia, Luna and Discord.
