Jasper, that doesn't necessarily mean they love Stalin so much. Stalingrad is also the name of the city that heroically fought off the Germans. When Leningrad chose to become St. Petersburg again, many people were against it, because Leningrad was the city that was nearly starved to death by the Germans, but had stood firm and had prevailed.

I am anti-Stalin. He killed too many people (the vast majority of them without any reason whatsoever) to be loved by me. He did some good for the nation, but the death and destruction he caused weigh far heavier for me.
