Not sure what the roll eyes is for. Are you sarcastically saying this? But yes - I think I do have first hand experience. For me porn made women less real to me. It made me feel like they weren't people, that they were just for sex. I tried a porn-free trial and starting getting that empathy back - I could feel things for women.
Any rate - my statement seems pretty objectively valid with any basic understanding of conditioning.

That's true. 3D movies, Transformers action schlock and Lord of the Rings style epic movies are the same as some cave paintings and really old black and white photographs.
