I don't think there's anything weird about that, honestly. In fiction there are certain roles and character types that are mostly filled by male characters and others that are mostly filled by female characters, but that doesn't mean that those roles are inherently masculine/feminine or that women who identify most with characters of a type that happens to be mostly male must have gender issues. The whole thing is mostly pretty arbitrary. And male characters, I think, have a greater diversity in the types/roles available to them anyway.
