"The majority I would class as coming from the view of 'I don't want reality to intrude on my porn experience.'"
Herein lies the problem IMHO. Porn is fantasy and nobody using it wants any sort of reality to encorach on their 'enjoyment' of it. In that respect men are often able to compartmentalise their thoughts/feelings where I for one - and I suspect most women - would not be.
"It's selling an ideal that doesn't exist, giving men unrealistic views and expectations of women."
Isn't that the point, though? It's selling an unattainable ideal. If it sold the reality (sex is, after all, a messy business) then, well, it wouldn't sell at all, would it? We all like to fantasise about unattainable things (buying a condo on Maui is a particular favourite of mine). Porn caters to what is expected of men's sexual fantasies (compliant women who will do anything).
"For every "law student making a fast buck", there's also one doing it so she can pay her rent and feed her kids, and would rather do anything instead of shake her ass for a bunch of random men. For every woman who finds it empowering, there are countless others who hate it but have no choice."
Whilst valid, this argument is simply not powerful enough. There are billions of people around the globe who do jobs that they hate in order to keep a roof over their heads. In that respect the sex industry is nothing special. Now trafficking and outright sexual abuse - there's the differentiator.
"However, if I were living with a man I had met in my twenties, before my feminist ideas were as fully formed as they are now, with whom I'd had children, who had been my best friend and companion and lover for years, then I might feel the need to compromise and to tolerate a behaviour that I found disgusting and turned me off him."
This is by far the most interesting point I have read here - what happens if I change over time but he doesn't? Beacuse of feminist ideals should I cast him loose purely because I've changed even if I still love him for all the other reasons? That one is really tough.
