This is an exceptional Ted Talks video by Jason Katz "An author, filmmaker, educator and social theorist, Katz has worked in gender violence prevention work with diverse groups of men and boys in sports culture and the military, and has pioneered work in critical media literacy.Katz is the creator and co-founder of the Mentors in Violence Prevention (MVP) program. This particular video is on why men are such a key figure in attempting to understand Intimate Partner Violence. He goes on to promote the use of speaking up within our friend environments and really getting at some of the main issues. At some point Jason Katz goes onto say that instead of treating people in a binary fashion of men and women we should really treat everyone as bystanders.
