Couple of points. Firstly it seems like the debate is becoming a little polarised with a number of people effectively saying that all porn is bad in itself, even where it's evidently consensual, for example, a couple making an amateur film on a webcam and are charging £5 a view online. Is that the case Elizabetth/ Tamz etc. or do those you are against porn believe that certain forms of porn are acceptable? Is it the point at which money becomes involved that it becomes wrong and if so, why? If I open a site offering people £100 for each clip like those above, does that make those clips somehow wrong?
Secondly, it seems that people are throwing out very strong views as statements rather than opinions, e.g. "A good bit of what is in porn, particularly hardcore is just filmed rape". Is it really? A statement suggesting that one of the most serious offences against the person is the norm in the industry would for me need a lot of validation, not just snippets of interviews. If there is evidence that is indeed the case, then it would be pretty interesting reading.
Equally, a view like "the essential nature of the porn industry is to keep pushing boundaries" would need some evidence. Really? I know that with the internet, there is incredibly extreme stuff on the net, but is this what is driving the porn industry? In this case I believe that the fastest growing porn sites by some margin are the entirely amateur sites, e.g. youporn.com, yuvutu.com, pornotube.com etc. which have amateurs posting webcam footage, very much like youtube.com. There's actually an article about it in The Times today. Again, if the amount of people viewing extreme porn is growing significatnly (rather than simply the number of sites) then I'd be very interested in seeing the evidence.
Thirdly, you can't just ignore contrary evidence of the other point of view. For example:
Madamez: listening to the youtube postings (and others it links through to) it's hard not to say that there are clearly problems with the porn industry which cannot be ignored.
Elizabetth: it's pointless and entirely recidivist to dismiss someone with a contrary point of view, e.g. Nina Hartley, as simply being a stooge of the industry and take her quotes out of context.
There's a great book, published 2003 which features a fairly long interview with Nina Hartley and various other figures in the US porn industry called "Once More with Feeling" and which highlights the ambiguities of the industry and the participants in it. I'd really recommend reading it. What it highlights, amongst other things, is that in the professional porn industry there are a wide array of people and companies involved.
It seems to me that perhaps the problem with porn is the lack of regulation in the industry, beyond fairly basic regulation. Would this affect people's view? I suspect incidentally, at least part of the reason doesn't have any system of regulation is that (a) no government is going to put one in place as it effectively condones the industry thereby losing them votes and (b) in any event it would require an effective system of reporting work it to work which it would struggle to have.
