Isn't it funny how easily some people bark up the wrong tree?! For the record - I LOVE porn - can't get enough of it, and I don't mean the marshmallow variety that many people here will only entertain. So, there you have it. Re-read the entire thread if you need to satisfy yourself that that's not a contradiction. I guarantee you'll not find one. Indeed, just re-read the OP question. Would an anti-porn proponent really pose such a question in that way?!
I don't know about him (though I am getting that impression), but I can assure you that at least for me your motives and purposes are fully irrelevant. I would just expect you to support your assertions better than via what _other_ women think about them. Which is a non-sequitur of epic proportions.
What makes it epic is that you haven't even provided evidence that, say, "most women think porn actresses have low self esteem"... which would still be a non-sequitur. You're attempting to bridge straight from "most women wouldn't do that" to a fully disconnected pop-psych conclusion.
The fact is, just about any think you can think of, you can find a majority group which wouldn't like doing that. Maybe even feel very strongly against doing that. It doesn't prove anything.
E.g., most men would hate to have sex with another man. Even those of us who don't mind someone else's doing it (I'm not gonna tell consenting adults what to do), wouldn't do it ourselves. There's a hard-wired response in there. But 10% of the people simply are wired differently.
E.g., most people of both sexes would really hate a job as a programmer. Even the thought of sitting with a computer and almost no human interaction (other than 10 minutes at the water cooler and a weekly team meeting) is most people's idea of pure torture. But some people actually like doing just that.
You simply can't bridge from "they're different from the majority" straight to "they have low self esteem" like that. You have proven _no_ evidence whatsoever of that critical "low self esteem" claim. All you do is a bunch of handwaving around something that just doesn't bridge that gap. You need a few more "X=>Y" propositions in there to connect your (so far fully irrelevant) evidence to your conclusion.
But, at any rate, your motives (if any) are fully irrelevant. If your data supports your assertions, it will still do so regardless of whether you're for or against porn or fully neutral.
