I agree. You have to remember it's a movie, not real. I don't mind it. I have a bootleg copy long before Criterion put it out and I have the box from Criterion. I have read books written by deSade and I have seen and read far worse. I used to belong to 2 forums that deal with actual horror so this stuff doesn't phase me.
I think having a certain set of pre-saved filters/search terms on pornhub would be more relevant for not being phased by the movie.
