UpABitLate your comment seems to apply that a porn for women (however hard it might be to imagine such a thing) would not be morally erosive, addictive, dehumanising, violent, nihilistic and all the things we associate with male produced porn. What basis have you got for believing such a thing?
I suppose the question I'm asking is this: Is it just porn (defined as commercial visual sexual stimuli) produced by and for men that is unethical/damaging - or is porn inherently so, regardless of who it is created by and for?
The further question implied by this question is this: If women were fully sexually empowered, would their porn and sexual culture be humane and empathetic? Or would there exist women, independent of patriarchy, aroused by violence/children/animals (and we know they exist already, however few in number they might be)?
If it's the latter then the project of giving more power to women to create and consume their own porn would be doomed to failure, because it would end up just as corrupt as the patriarchal version. Maybe women would become aroused by women degrading other women - or by men being degraded. New sexual scripts of power could emerge.
I think porn is inherently immoral. Even if patriarchy collapsed tomorrow, the porn that would emerge would still come with big moral problems, because it always transfers sex from a human context to a commercial one whereby people are abstracted into one-dimensional features of an individual's sexual fantasy.
