Honestly this is what I don't understand about her, especially when her words and attitude go directly against the themes that the books she wrote outlined. For example, Hermione being called slurs like mudblood and the other characters sticking up for her. Hagrid who has to live with himself as part giant and is considered a threat by most of the wizarding world, but those who are close and know him, know that hes a kind hearted person.

In almost every instance where a character has to deal with something about themselves that's different than the others, the lesson is that everyone should always accept who they are and that they're valid in being who or what they are.

Instead in real life she just ignores all of this and just acts like a disgusting piece of shit, and you have to wonder how she even wrote these books when she lives her days talking and acting like this.
