So been out most of the day and come back to this...it's enough to make one despair.
Right difference between a gang-bang anal rape scene and an underwater welder?
You said no-one enjoys receiving in an anal gangbang scene? That's the difference right there: the object of your job is your degradation and your suffering is a required (I.e.: essential) product. An underwater welder may well accept the risk of injury but his injuries are neither the intention nor essential to his job!! That they happen is the reason he commands the pay he does. Their possibility is not the necessity though.
Finally an idea of human nature and a general idea of human action will make it fairly clear how damaging pornography is.
Human nature is good- it strives to excellence and beauty and goodness. It is, however, marred by a terrible weakness and a terrible propensity to fall into what used to be known as base passions. Our society, and our socialisation generally, attempts to raise each generation to fight ones own base passions in order to achieve more excellent things like marriage and family and having children or doing things like giving your life over to helping those less fortunate etc. These require a level of self-discipline and self-mastery that falling into base passion derails. I am talking of things like lust (the sexually based emotion that attempts to use the other rather than love them) or lying to make ones life easier. Drunkenness does the same thing- it robs one of self-control and a life given to drunkenness is a life often destroyed. Read the posts in the relationship section that mention alcoholism. Also the lack of control of appetite: read all the threads about people's regret at
Underneath this there are what used to be called morbid passions: the rage that can lead to violence, uncontrolled lust and anger that can lead to rape and the like.
Porn as I remember it in all the magazines and the like used to be aimed at arousing base passions. This is problematic enough. Porn from what I've heard and read just on this thread is aimed at arousing morbid passions- arousing violence and arousing anger. Of arousing a selfishness so deep that it then overwhelms the natural empathy and sympathy people have when viewing others. As a society we seem to be walking away from teaching our children the value of self-control, of the value of taming our uncontrolled nature.
Such an analysis of action and of human nature makes the danger of porn obvious from the moral point of view. Everyone else has detailed again and again the danger to bodily integrity and psychosexual danger that porn poses in normalising brutality in sexual relationships.
So, to return to your original points coin- yes, ultimately the origin of this mans actions are found in his own moral freedom. But that doesn't mean that he wasn't helped along the way by his use of violent porn.
The only way you can argue what you seem to be arguing comes from a sort of transactional theory of action- provided I am paid for my actions I am therefore not abused or used and since you seem to be suggesting that most porn actresses and actors seem to be paid therefore their choices must be respected. I think that's arrant nonsense because humans are more than transactions.
Along with others I cannot tell- you may be a troll, or you may simply be so horrifically brutalised by your life that you are unable to see your own pain: but it is just that, pain. That does not mean it is too late to escape or to find a life beyond it. It does, however, mean that the industry you are defending is heavily responsible for your anguish. For all I know you may not be who you say- you may be someone paid by pornographers to defend pornography on forums just like this. It doesn't make the damage of porn any less real.
