We had a discussion about pornography on the last day of last term in English, since we were reading various articles in gender discourse. One of the issues is that some people believe that it is demeaning for women (no mention about men, but then I expect most porn is of women rather than men), since it turns them into sex objects. I suppose it also depends on what is actually being portrayed in the porn, and I didn't see anything mentioned about that (in the linked PCWorld article), just that some attorney said how disgusting it was.
I think though that if people (men or women) consent to be in the porn industry, then that is their choice. And there is nothing wrong in viewing it if the people in it are consenting, even though I wouldn't myself.
