When the hammer and sickle were part of the glorification of the communist period at the opening of the Olympic Games, I thought of my family who starved to death!!! at the time of the Stalin's Holodomor
I'm disagree with you. This part of the open ceremony wasn't a glorification of communist era at all! It was shown a great influence of the industrial period of the first Soviet years: all these machines and mechanisms, collectivization, this red color as symbol of blood, little figures of participants acting as parts of a great machine called Soviet republic. This scene was done in stylistics of Suprematism (Malevich, Rodchenko etc).
http://rusplt.ru/policy/olimpiada-v-sochi-otkryita-7956.htmlThis was a symbolic interpretation of pain and disharmony. It showed how a normal human civilization of Russians had changed into depersonalized masses. It was more a symbol of tragedy of the Soviet people, but not a glorification.
These hammer and sickle were parts of a very famous Soviet sculpture Worker and Kolkhoz Woman (showed at the World's Fair in 1937), a famous symbol of the Soviet period, was also showed crashed on the ceremony. You could see only parts of it (head, hammer and sickle were showed apart.

It's a pity, you didn't catch the main idea, though everything on the ceremony was shouting about it, even music with its cacophonic and disharmonic tunes of Stravinsky and Schnitke.
Also there are rules of the Olympic Comittee which prohibit to show tragic times and wars in the historical parts of the ceremonies. That's why also the Second World War wasn't shown in the opening Ceremony in Sochi.
