Uh, the hammer and sickle was just a symbol for the working class in communism, and was the flag of the USSR for many years.
It also has little to do with the national socialists in meaning.
Hurdur?
Except the soviets didn't commit genocide and force an entire people into camps to be overcrowded, starved, murdered, and burned. Oh and then there's that whole world conquest thing, waging war all through Europe and causing the most violent and bloody conflict the world has ever seen.
You simply cannot compare the national socialist regime to the USSR.
Yeah, soviets were angels, they did nothing bad to us, only sent tens of thousands people from my country to Siberian prison camps, just because these people loved and worked for Estonia when it was unoccupied, where they died to starvation, overworking, bad living conditions.
