Joe Biden has acknowledged both that women can be violent and that they benefit from unfair protection from retaliation. He did this during US Senate hearings concerning the Violence Against Women Act on December 11, 1990:
"In my house, being raised with a sister and three brothers, there was an absolute - it was a nuclear sanction, if under any circumstances, for any reason, no matter how justified, even self-defense - if you ever touched your sister, not figuratively, literally. My sister, who is my best friend, my campaign manager, my confidante, grew up with absolute impunity in our household. And I have the bruises to prove it. I mean that sincerely. I am not exaggerating when I say that."
