Hollywood has been making "critically acclaimed" movies that sympathetically portray perversion for years. Doesn't anyone remember "Midnight Cowboy" and "Pretty Woman" glamorizing prostitution? "Mystic River" attempts to make the audience sympathize with a man who murders an innocent man in cold blood, because he thinks the guy might have killed his daughter. "De Lovely" portrays Cole Porter as just another homo whose lifestyle is grand and whose wife loves him anyway, and makes her the heavy when she gets tired of his cheating on her with men and wants a baby. "Kill Bill" desensitizes the audience to horrible violence and gore, all fair in the name of "revenge." Critics loved these movies. Art is supposed to challenge the blandness of the bourgeoisie, dont'cha know.
People need to look over the list of best picture oscars. They are full of things that most of us consider wrong or immoral--Grand Hotel, Gone With the Wind, Casablanca, The Lost Weekend, All About Eve, From Here to Eternity, The Apartment, Tom Jones, etc. Immorality is nothing new as far as fodder for film plots.
