I never understood, why so many women look down on (female) porn stars.
That's a good & big question, Caroline. I could mention factors like latent envy, snobbery, and the force of traditional morality, but these are simplistic notions, just scratching the surface. I suppose that some women get an ego boost from looking down on other women as sluts & whores (as many men do with rather different underlying motivations). And what better target for them than porn-stars? Still it's a complex issue, perhaps best explored initially by other women such as yourself.

Its one of the few movie genres, where women play the most important part.
I was reminded of this old article which treats this topic nicely. Unfortunately, i could only find this truncated abstract, but it's worth a read if you're really interested and can dig it up in a good library.

Also, i remember Camilia Paglia, an American celebrity academic, was quite a vocal champion of a sort of pro-porn feminism back in the 90's, but i haven't heard anything from her for years.
