Noble feminism?

David Huffman is a student at the University of New Hampshire. Being a bold soul, he decided to attend a feminist poetry reading and story telling event. He was only allowed to stay for the nicer part of the proceedings - but this was more than enough to reveal the less than lovely side of the campus sisterhood. As David describes it,

Throughout the first part of the evening, the girls sang songs about "man-hating" and glamorized it. They also read poetry about castration and cutting off men's genitalia. The girls wore scissors around their necks. It was angry, violent, hateful speech.

As David quite rightly points out, this does not quite seem to measure up to feminists' own supposed commitment to tolerance and diversity. Are they not in contravention of their own left-wing campus codes?
