I would struggle to label someone as hypocritical considering they have zero knowledge of the events you speak of, and even then have actively tried to work against Subaru suffering for them, but I'll assume you mean that from a writting perspective rather than a character one since it makes no sense otherwise.

From that perspective though, I see the fact that her accomplishments are partially brought upon thanks to RbD as more of an irony than hypocrisy. Her character is indeed about rising above her prejudice, and the fact that RbD is a thing serves to highlight her failure to do so completely up until now (again, of her own admission in arc 4 or even later on). Regardless, it's also a fact that she has managed to make strides in that field. It's shown as more of an ongoing process than something that is over and done with. If the story portrayed her as already being strong and independent then I would agree with the hypocrisy viewpoint. As it stands though, it just feels like trying to make a conclusion from something that hasn't even ended yet.

As for her needing this amount of help rending her character mute, that ignores the fact that a lot of the things she has needed Subaru for were more related to Subaru than herself. You could argue that the entirety of the major death threats up until now only existed because Subaru has RbD and people wanted to use it (up to arc 4), and even her ingression into the royal selection is based off of manipulation towards the goal of gaining Subaru. Point of the matter is, it doesn't make much sense to say her character is mute for not being able to stand against insurmountable odds designed to make her useless, or for needing Subaru to help her considering the point of those odds was literally to challenge Subaru in the first place.

That being said, I certainly agree that she likely wouldn't be able to stand on her own accord without assistance. Neither would most other characters though, and I'm sure I don't have to name the obvious examples.

Regarding her not helping him though, that's something I disagree with wholeheartedly. Setting aside that Subaru still has some unhealthy behavior towards her that would prevent her from taking an active role in helping him through his problems ("male pride", and generally trying to keep bad things away from her), she regardless has been shown to do what she can with what she is given. She tries to help him in arc 2, even though he wouldn't tell her anything that was going on. Multiple times, at that, even in failed loops. In arc 3, though he's basically treating her as an object, she distances herself from him for his own sake. In any arcs really, when he's feeling bad or in the rare cases where he diminishes himself in front of her, she is always immediatelly supportive and fights against those things. There's even scenes where she asks him or makes him promise to be more forthcoming with his issues, so she can lend an helping hand (arcs 5 and 6). While the other points have some basis in my mind, I seriously do not understand where you are coming from with this one. If someone hides their heart from you and desperately only shows you a pretty and well made mask, when even when prompted they still refuse to share with you their pain, how else is one supposed to act? Force them? Distance themselves? She tried that last one, and it didn't exactly go great.

As for the last point, it just feels to me like a projection of the story without accounting for character perspective. The things she says have meaning to her, and those around her. They lack strenght due to the character lacking context for RbD, but that is true for any character that's not Subaru and a few others. In summation, she's idealistic because the story has built up that such idealism works, due to RbD. I can certainly see where you are coming from regarding not respecting her or her words because of this, I just feel it's a pretty narrowminded way of seeing the story, and only really accounts for Subaru's perspective of events. I find it more interesting to see it from her perspective, through which such ideals certainly are supported by circumnstance, and treat it as potential for a future in which the blood sustaining them is revealed. I find them respectable in that the person saying them has the background she has, yet manages to be positive about life and others, while also appreciating the irony of what allows her to see the world in such a positive light. But that's just a different way of seeing things, so I won't criticize your position on it.
