Porn consumption isn't proven to cause violent and aggressive behaviors In fact, the inverse is likely true, those who are violent tend not to have as many intimate partners and so will have higher rates of porn consumption. There are a number of studies that have found sexual violence and rape to be negatively correlated with porn use suggesting that having an outlet rather than bottling up their sexual urges is better. That being said, the content of the porn does have an impact, so it would be better to advocate for respectful and consent positive porn than to try and ban it.
