Bolshevics weren't Russian, nor a majority amongst any other nation

This video clip is about the history of Bolshevism, which today is called Communism. But the fact is, that the Bolshevic Revolution in Russia wasn't a Russian national revolution. On the contrary, many Russians were killed as a result of it, like all other nations in what became later the Soviet Union. Nor were the Bolshevics/Communists the majority amongst any other nation, including the Jews.
