Jackson Katz is an educator, author, filmmaker and cultural theorist. He is co-founder of Mentors in Violence Prevention (MVP), one of the longest-running and most widely influential gender violence prevention programmes in North America, and the first major programme of its kind in sports culture and the military, teaching compassion to bystanders of sexual violence and how they might intervene - the so-called "bystander" approach. Since 1997 Katz has run MVP Strategies, which provides gender violence prevention/leadership training to institutions in the public and private sectors in US and around the world. He's written two books, The Macho Paradox: Why Some Men Hurt Women and How all Men Can Help, and Man Enough? Donald Trump, Hillary Clinton and the Politics of Presidential Masculinity. Katz will speak to Richard about this week's revelations about the behaviour of mega movie mogul Harvey Weinstein.
