After reading an overview of the film, I’m not exactly sure the movie is exactly a defense of pedophilia… And art reflects life. They already make “dolls”, some of which are designed to look of questionable age. If robotics advance to the point where we have androids with artificial intelligence… Well, you can bet your britches there will be a market for this sort of depravity.
I’m also not sold that “became people accept LGBT people folks will accept pedophiles”. We’re thankfully having a more progressive view of consent and are starting to realize that a difference in power dynamic can actually invalidate consent… For pedophilia to be accepted, we’ll have to back track on that.
