The crowd at tonight’s Democratic debate laughed as Joe Biden said we must “keep punching at” how women are treated.

Biden claimed credit for starting a movement on college campuses to make students “safer.”

He said there is a need to “fundamentally change the culture.

“No man has a right to raise a hand to a woman in anger, other than in self-defense and that rarely ever occurs,” Biden said.

“And so we have to just change the culture, period. And keep punching at it and punching at it and punching at it,” he continued as snickers and audible laughs rose up.

“No, I really mean it,” Biden said, “it’s a gigantic issue and we have to make it clear from the top from the president on down that we will not tolerate it.

“We will not tolerate this culture.”

As the camera cut to a wider shot, rival Kamala Harris could be seen smirking.
