If you suggest restrictions you will find a great many people agreeing largely from emotional basis. Oh and for the record this is far from rabid. This is what I read and write to relax from much more intense material related to my specific field. And given that these two focus on control exclusively, they must be even more at fault, even closer to being a root cause. Notice that I am only applying your argument.
Erotic material is technically for personal enjoyment and immediate sexual gratification.
It is bought and sold freely, and so increases peacefull pleasure enormously. That is their only power and means of achieving the ends they desire. Attempting to force one's ideas on others is just as distasteful to me banning other's ideas. Fewer mores condemning it, as long as we do not promote erotic material. I am forced to view erotic material if I choose to watch television.
