Ok.. Let me try to explain this again..
I view porn as objectifying and degrading to women, I have a grilfriend, and I view watching porn while having a girlfriend as a form of cheating, and especially if your girflriend doesnt like it or the idea of you watching it, it then becomes a lack of respect for her.
If someone chooses to view porn, I am not going to shun them. I am not going to say "OMG YOU WATCH PORN YOU ARE A BAD PERSON". Kinda the same thing with the pot subject.. If you think pot is bad/wrong, but you have friends that do it and you are ok with them and remain friends with them.
When I say I dont think it's wrong, etc, I mean that I am not going to tell someone what to do. I am merely stating my point of view on porn, I am not telling someone what to do. Hence, if they choose to view porn, I'll take it as their decision, not mine, and I wont say a thing. I may not like it, but it damages me in no way, it's not my life, and sure it isn't something I myself would do or like, but they arent me.
Thats what I mean when I say I dont think porn is WRONG if you watch it. But just because I think it is wrong or not, doesnt mean I also cant think that it does objectify some women in some way.
Why the need for the placeholder? That's the same as saying that someone went out and slept with someone else because they weren't getting any, so they needed a placeholder. Sure, it's another extreme comparison, but still, the principle is the same. The placeholder.
The difference is that I fantasize about my girlfriend, not another girl. When you watch porn, you're watching another girl. You are getting off to another girl. You aren't actually physically touching or with that other girl at the time, but it is her and the images of her on the screen that get you off.
