That's exactly the point. Sometimes breaking a persons ribs is a good thing. The medical argument I made was just meant as an example of a positive use of porn. There are surely others, such as in sexual dysfunction therapies, and perhaps in spicing up intimate relations within long term relationships. It's just not a black and white situation where porn should clearly be cast as a societal evil. My goal was to illustrate at least one uncontroversial use of porn that was positive. Someone willing to concede this point must then think more carefully about which uses of porn are positive and which are negative rather than dismissing them all as inherently negative.
