I do regret some of my phrasing. It had been while since I had seen Rope, so I re-watched it just now.
Considering its reputation, the only real "sexual" anything (O.K... we won't use the word "fluid") lies in Brandon's talk of the "thrill" of murder and the loose connection to a famous crime involving lovers. Otherwise it doesn't exactly deserved so much focus in the history books as, say, Strangers On The Train which is a bit more straight-forward. It is like all of the hoopty-doo about Mrs. Danvers in Rebecca even though she only gets excited over ladies lingerie.
What strikes me on the most recent viewing is how much it resembles Crossfire, Gentleman's Agreement and the Nuremberg Trials. By 1948, President Truman was desegregating the military as yet another attack on America's prejudices of yesteryear, post WW2 atrocities. A lot of movies of this era were questioning mankind's love of "master races". I won't go further in how it also could bring up political discussions for today (i.e. all of the "Alt White" business), but... yeah... movies of this era can offer much to learn for today. Stewart's Rupert was quite snobbish in his youth discussing "superior beings" but he has evolved over time and understands that his way of thinking should not be society's way of thinking. He is shocked to realize that his "students" would take it to the next level. Victim David is viewed as inferior although we are not explained why. Was he Jewish?
For the most part, John Dall's Brandon is the cold-blooded one who treats murder as just a joke and enjoys having a cocktail party over it. Granger's Philip is less comfortable with murder since he is the sensitive one. Intriguingly his astrological sign is brought up by Mrs. Atwater (Constance Collier) as a "moon child", a very emotional Cancer... and too emotional to treat murder as just a joke. Even the chicken strangle story upsets him. We, of course, don't know Brandon's sign, but it is implied that he lacks "water" (feeling). Likewise, there is much drinking but we never really see Brandon drinking. He just serves liquids to those who are "too sensitive". Likewise, Rupert is also analytical and "cool", but after discovering what happened and shooting a gun out the window to alert the neighbors, he starts to break down on the couch, feeling considerable emotion he hadn't felt in the past.
Nothing wrong with your phrasing....censorship has probably has a lot to do with the cutting down of the homosexual elements of the story
