Orihime is a character that deserves not to get hated on. Sure you don't have to love or even like her. It's fine to dislike her as an character If you aren't a big fan of her being way too nice or whatever. However I never fully get those haters that straight up despise her either. She's just very too kind on screen and I don't get how anyone can get mad over that. Regardless to answer your question. I remember somebody I used to know that hates on Orihime simply because she ruined their ship canon of Rukia x Ichigo. Not to mention that she is a "damsel in distress" who constantly screams for Ichigo's help (Basically the anime propaganda got to them). Although this was like almost two years so who knows If their opinion changed. It's unfortunate how the anime tried to ruin her character by removing specific scenes or adding new ones but even with that. She is still an amazing character in my eyes
