Men who enjoy 'rape' porn: Why? And how does this affect your attitudes towards women IRL?

To be more specific--anything that features a woman who is obviously in pain or distress outside of a controlled BDSM environment, or anything that is portrayed as being nonconsensual or demoralizing.

And how do the women in your life feel about it?

EDIT: Want to add the following:

It just seems funny to me that pornography depicting rape is acceptable and a lot of people say "Oh, it has nothing to do with what I want in real life," but replace "rape" with "children" and you've got a shitstorm on your hands.

• Rape = crime
• Child molestation = crime
• Rape porn = okay
• Child porn = not okay

Now, a lot of rape porn is staged, but (from what I gathered from the recent pedo IAmA's) a lot of child porn is computer-generated...no one is getting hurt in either situation, but the latter will land you in jail while the former is considered harmless.

Explain?
