You can't always be sure people are consenting adults in any movie. Underground porn is more likely to have non-consenting parties than the big name porn.

There's nothing wrong with material solely meant for masturbation and sexual pleasure, IMO.

I'm not arguing that most women (not sure about men) in the adult industry seem to have been abused when they were younger. I don't know that (it's most) for a fact, but I've seen a lot who said they were. Again, my point is, in the USA, we still have to give people freedom, even if their decisions are detrimental to themselves. It would be too easy for people in power to determine that anyone weird, strange or unusual has a mental problem and needs to be controlled if we don't give individuals their freedom. As long as you're not hurting others or infringing on their rights, you should be free to do as you wish, IMO. But your body is yours, to do with as you please.

I wouldn't be offended or upset if my sister was in porn by her own choice. My mom's highly unlikely to be in porn because of her age, besides not wanting to be (and my sister doesn't want to be, either).

People have been sexually abused who are in mainstream movies, sometimes violent ones. Should we avoid those? To say we should determine who's been abused and who hasn't, and to avoid their movies, makes no sense to me.
