Who knows, but I seriously doubt that softcore porn does more damage to our moral fibre than Power Rangers and Bruce Willis films. I don't think people learn violence from the movies they learn it at home and on the street. None of these issues has a simple cause and I seriously doubt that any limitation on free speech will help reduce the problem of violence towards women, children or others. I suspect that the problem will get worse because it will be more difficult to talk about it. I think we would suffer a great loss of freedom and women would suffer the most and gain nothing positive.
Women lose freedom too.
I think that the assumption that women need protection from speech is harmful to women. Sorry to ramble so much, it's just that this stuff has been on my mind a bit lately. Another young woman sleeps with the wrong local on a Pacific island, after which he feels entitled to show up and rape her whenever he feels like it. The women in all three movies were essentially objects at the disposal of the men around them. There is a curious double standard in our society that movies that portray blacks, for example, as objects would not be acceptable, but women can be objectified and no-one really takes notice or agrees that it exposes a social problem and has pernicious effects.
