It's really all the bell curve concept. We can adjust what is an acceptable range, but "outliers" will always exist. I think the line should be drawn at the line of legally informed/educated consent. The outliers can then be dealt with by the law and activists. If we make all consensual porn legal, there will still be outliers willing to produce and buy outside of that. If we made all porn illegal (which is NOT a good idea, by the way), then the outlier range is much more broad, and those willing to produce outlying content will have more to profit from. Money over human well being is generally always the argument. Too many people are willing to overlook the destruction of a human if it puts money in their pocket.
