Sometimes people are the architects of their own misfortune.
I'm sure we've all known some.
Creepy, predatory guys who complain they never get laid, is an example.
Or aggressive, bullying kids who are unpopular.
However, being aware of victim blaming, has the underlying concept of trying to understand people's actions (like the bully).
But where victim blaming really becomes significant is when you are blaming a person for someone else's actions. With little or no reason.
Like the gaslighting of 'she made me hit her'.
In terms of rape culture, it's extremely significant. Because traditionally women who acted or behaved in a certain way, wore revealing clothing, etc, were considered 'less than' and therefore not worthy of the same consideration as women who didn't.
A misogynistic concept if ever there was one.
Allowing men to view women as two sides of the same coin. Madonna/whore. So any bad behaviour on their part is justified, as long as the woman falls into the whore category. So asking a woman what she was wearing, or what she was doing, is the fast track way to eke out any 'undesirable' behaviour that can then justify the behaviour of someone else entirely
In reality, women who are raped do not fall into any category other than that of woman.
So being aware of victim blaming has a double purpose. Firstly that the actions of a rapist are dependent on them and them alone, and that men are disabused of the fond notion that they must the arbiters of women's behaviour.
Likewise blaming a woman for not leaving an abusive man. Shifting focus on to her, rather than him.
