I think it's hard to say that consumers of a product or service are responsible for negative aspects of the purveyors of that product or service. It's fairly similar to the argument that many give for being vegetarians, namely that by partaking in the product offered to them (that of eating meat), they are therefore responsible for the killing of animals. Sure, there is some truth to that, if there wasn't a market for beef, cows wouldn't be killed, but there clearly IS a market for beef, otherwise they wouldn't be selling it. In that analogy, the cows are the porn actors and actresses, in case you needed clarification.
The problem here is that some women are lamenting their decisions to be porn actresses, that's fine, plenty of people lament their situations. I've lamented my decision to get a degree in Philosophy for the better part of 5 years, but I live with it because I can't change the past. The only thing that you can do is change the future. I understand that we don't all have the power to do that to the degree that we want to, but we HAVE to live with our choices and our consequences. Asking anything else is trying to shirk responsibility and accountability.
In short, porn actors and actresses chose this life, perhaps they feel like it was a poor choice, perhaps it WAS a poor choice, but they have to live with the consequences of their actions. You can't blame consumers for the affects on the suppliers. If porn actors and actresses want to change their lives, they can do that. I'm not saying it's going to be easy, but rarely is anything worth having that is easily obtained.
And please don't tell me about the different sociological pressures that are put on them, I'm aware of them. Anyone with the right attitude, habits and desire can find a way to make their lives better regardless of their circumstances. I work 4 jobs from 8am to midnight straight 7 days a week so I can make up for my mistake that I mentioned earlier and all of that hard work is starting to pay off. If I can do it without any support to the degree that I am, then they can surely do it too.
It's just easier to make excuses.
