I'm a sociologist, and I start from the assumption that men are not born johns, rapists, and murderers. I speak about that from sociological research. I speak about that as a feminist. I speak about that as the mother of a son. We have to accept that men are perpetrating the vast majority of violence against women and children. Is this a biological mix-up in masculinity, or is there something cultural going on? I would argue without doubt that it is something cultural because we do not want to think that men are flawed in their biology.
Because we are seeing increased rates of violence against women and children today, we have to ask, what has happened in the last 10 to 15 years that has shifted profoundly the way that men think about sex and sexuality? The answer to that is pornography. I would argue that if we really want to stop men from doing violence against women, we have to stop saying “boys will be boys” and understand the way in which they are socialized.
We now have longitudinal data; we are following boys to see what happens. Because of what we know from longitudinal data, we can argue that it's not just correlation that men who look at porn are also likely to do violence. It's actually causation. When you use longitudinal data, you're following them through their lifestyle.
I would also argue that we cannot assume that men are born with a desire to do violence against women and children. I believe it is pornography that is playing a profound effect here. Unless we deal with it, we just sell our boys short, and we'll profoundly sell our girls and our women short.
