If you enter into a relationship with a KNOWN ABUSER, WITHOUT COERCION, then yes, YOU are responsible for the damage you recieve. I didn't say victims of abuse are responsible. Furthermore, I'm not victim-blaming. What I'm saying is, if you enter voluntarily into a relationship with a known abuser, then you are intentionally turning yourself into a victim. Sounds pretty fucking crazy to me to do such a thing. Here's another analogy:
You go to the pound to adopt a dog. There you find a vicious snarling pit bull. You're warned not to to take him home, because he'll hurt you. But, for whatever reason, you decide to adopt the dog, and when it mauls you, it sure as hell ain't the dog's fault. EXACTLY the same as entering into a relationship with a person with a known history of abuse. By getting involved with such a person, you're inviting them to turn you into a victim.
