Some people just read what they want to into ANYTHING.
I thought the opening ceremonies were mostly well done although I can certainly understand objections to Yoko Ono & Susan Sarandon neither actually did anything objectionable during the ceremony. Unless you object to Imagine, which by now is a classic. (I would have liked to see a whole covey of the great Italian stars accompanying Loren. Gina Lollobrigida, Claudia Cardinale, etc. -- assuming they're still alive.)
The original post seems like it was written by somebody who didn't know very much about Italian culture. For the most part, the ceremonies celebrated Italian culture, which seems appropriate for the venue--from the Renaissance/Baroque era to Turin's modern era as the automotive capital of Italy. There was also opera (Pavarotti and the trumphal march from Aida) & allusions to Commedia del'Arte. The sun and the moon globes looked to me like they were straight from illustrations from the Italian Renaissance.
The Ferrari was hardly "Brokeback Mountain." Neither was Luciano Pavarotti (well known womanizer!!!). He was in good voice, amazing for his age -- although didn't try the high C in Nessum Dorma. Shades of the 1990 World Cup!
And--what on earth is "gay" about Venus on the half shell? The Botticelli painting it is based on is a celebration of love and beautiful women.
