well, I think the real problem is that it's like prostitution only even more pervasive. It's here, it's here to stay and getting worse. That's the independent reality.
For people who say that men can control themselves and don't have to use it - well, but the thing is a helluva lot of men don't. It's like fundamentalist christians saying that you can keep yourself virgins until marriage. It might in their view be the better way, but it's often not happening. Better to adjust to the situation as it is, rather than as it should be.
So I'd be happy to see guidelines brought in to govern it and penalties for not adhering to those guidelines. The problem at that point is not the companies / individuals who keep to those guidelines, it's the companies and individuals who don't. Probably the vast majority sadly :s
There won't be any one single solution to this problem but a lot of the 'nicer' men or women who do care about the people producing it would be able to search out the more ethical stuff.
How you curtail the viewing for people who don't care, or the extreme and rotten stuff, I really don't know. Given how many resources have to be sunk into minimizing the amount of child pornography, a relatively tiny area of porn, it's hard to see how you could effectively prevent the making of exploitative adult porn.
Maybe the best way forward generally is to tackle the ISPs etc. Plus talking to teens about the nature of the sex shown and outlining the exploitative nature of it. That's something people can actually do about it at a personal level.
.... I may be overthinking this a lot in completely the wrong place ...
