No, you're a little off. If we accept your example, then you're arguing that murder victims are responsible for fixing murders.

There are plenty of differences between murder and sexism (you can only murder a single person and once, sexism has oppressed multiple people multiple times for centuries... millennia?, sexism is a social/cultural phenomenon perpetuated by the patriarchy, murder isn't). The analogy really just doesn't fit.

The responsibility for fixing a problem is never with the victim.
