First of all, it seems to me that we have two different discussions going on about the same point here. The calm debate from SugarB, and the emotional debate from SW. (Not meant as an insult). It seems to me an interesting dynamic.
Anyway,
Good point. I don't know either. Perhaps it's the same reason why VCP is illegal. Gave me something to think about.
If I sound callous, forgive me, I don't mean to. I'm going to to go on my opinion here, but I may be wrong. In the case of a physical condition in which your body causes you brain to misfire (siezures or diabetic blackout), or your brain is already misfiring on it's own (depression, anxiety, narcolepsy), you don't have a choice when or what is happening and you are not in control.
I don't mean to sound mean, I'm sorry if I do, but I'd imagine that it's the same reason why drunk people shouldn't drive, even though before the drunk driving laws were enacted, plenty of people didn't get into accidents. Something else is now controlling your mind and body.
I'm a big fan of Tera Patrick. She's intelligent, beautiful, a wonderful person, (met her in person on several occasions), hot and an honest performer. However, I don't watch only her. I watch a bunch of porn with people I don't know or are a particular fan of. Why? Not because I'm objectifying the people involved, but because I am aroused by the situation that's going on. The people involved have to be attractive to me, sure, but, I will not, for instance, get aroused by two men having sex no matter how good looking the guys involved are. It's just not my thing. Even SW was claiming that "marshmallow porn" wasn't his thing. Often it's the situation, not the people.
Actually, the reason I started making porn was because there wasn't enough of my fetish out there. I decided to make the fetish available myself.
It's more than the bodies, it's the fantasy. So though I do not enjoy sex with children, I don't even fantasize about it, but, given my particular fetish, I can understand that it's not the person, but the situation that is arousing.
And if one will call that "objectifying the performers", then one can say that equally about any movie that arouses emotion. When we watched "The Matrix", during the movie, did we really care about how Kenue Reeves felt while filming the scene? No, we cared about Neo. We cheered Neo when he dodged all those bullets and kicked the hell out of Agent Smith.
Porn contains sexually explicit material, but in it's basic purpose, it's still a movie designed to arouse feelings. That's why I feel the "objectifying" part of the argument, even though it includes child porn, is invalid.
