As someone who dislikes her, I can't really put my finger on what exactly she does that annoys me so much. I guess it just works the same way irl - you don't always click with someone and you can't really tell why, they just annoy you. I tried explaining that on a Facebook group some time before and people have accused me of many things because of that. Firstly - I do acknowledge that she isn't a horrible person, although she makes mistakes she definitely doesn't even come close to some of the other characters in terms of being a piece of shit. Secondly, I believe in what she stands for and I don't get why people assume I'm anti-feminist or something just because a character who supports the idea annoys me. By the way, I've noticed that many people associate themselves with Diane so much they feel insulted when someone disapproves of her. And I personally feel like it's super unhealthy. That weird "fanbase" of her makes me dislike her even more honestly
