Its also deeply culturally conditioned and mediated by a number of other factors.
That's the problem. Cultural conditioning makes sexual interest abnormal.
What does this have to do with pornography?
Sex is sex. Sexual interest is what pornography is all about.
This is nothing but a emotive tirade. Being in the Celestial room, could you engage in philosophical argumentation?
This is a philosophical argument. You're being obtuse.
I'm posing serious questions, and trying to elicit stimulating discussion/debate, and all I can get, for the most part, is a traditional Phil Donahue rant about silly religious taboos, the "naturalness" of sex, and how moral principles themselves are the cause of the very social pathologies they seek to ameliorate (rather than the "natural" human weaknesses and tendencies to unbridled apatite/desire satiation being the cause of the need for moral principles and ethical philosophy).
You are getting serious answers. Just because you don't agree with the thoughts doesn't mean they are not serious. From my point of view, your postulations are adolescent. I think I can hear giggling in the background as though a teenager were whispering about "naughty" things.
Your interest in this subject speaks much about you. I don't think anyone is buying the "interested only in the philosophy aspect" excuse.
