But what reason would anyone have to hate her? She's kind, sympathetic, supports her friends, tries her best to forge her own path and generally is awesome. I mean, I'd get disliking her if she was unkind or cruel to others, but... she's not. She really, really is not.

I suppose you could dislike the fact that she doesn't "kick as much ass" as the boys, but that isn't exactly *her* fault as we don't know what sorts of power levels etc she has.
