The main character is like super bitchy. She's like the internet. Anything the popular people do is something she hates and loathes purely on principal. It's a fucking comedy though and hard to mistake it as being serious. I'm too lazy to read the article but I'm sure it's probably pretty jokingly called "mean spirited" and this thread is mostly just people overreacting to a quote purposely taken out of context in order to cause a stir.
It'd probably help if you actually read the article, at least in part. You couldn't be more wrong.
