I havent read all of the pages but too the subject of porn being vegan, I take it as is porn ethical, my opinion is NO.
Theres lots of problems I can see with the porn industry making it very unethical in my eyes, e.g. > its all built around money with practically no-one in it for sheer joy of being exposed to the world and the ones that aren't paid regret it later on, the predators are far too many as are the prey, woman are constantly taken advantage of and pumped full of drugs and porn consumers would have no idea if the woman even consented to it or not, rape porn for example falls under the banner of porn as does fetish porn where woman are tied up, how do you even know that it isnt actually a rape scene that you are witnessing, you might opt for a lebian scene or a solo scene.. how do you know that the people involved are not desperately in need of cash and severely regretting that they are at that point however cannot see a way around it and are victims of the monetary system.
I think as much as people enjoy it and want to believe that there is good porn out there, these are selfish ideas to make it ok in ones own mind.
I have met a couple of victims of porn who regret it dearly, after being exploited to such an extent its not uncommon for such a person in such a stage of regret to feel suicidal enough to take there own life.
So long story short, my opinion is against porn altogether, I see too many victims, lots of exploitation, and quite frankly too many selfish perverts jacking off over drugged up woman at their computer desk that they will never have a chance with in the real world, disgusting...
Reminds me of a case I read where a guy went out and raped a heap of children after watching porn, more evidence that porn gives a pretty horrible message to people who somewhat think its ok to recreate what they are seeing.
