I remember hearing the "mind rape" descriptions of that scene when the movie was released. If the audience interprets a scene a certain way it's not the audience's fault it's the filmmaker's.
I have no real opinion on this particular scene. But the general idea that filmmaker's are at fault for audiences' interpretations is total bullshit!
All the time viewers are drawings outlandish conclusions from films that have nothing to do with the intentions of the people who made them.
