none of those people died as a result of Communism itself, rather because of the failings and brutality of the regimes which implemented Communist ideology. Whereas Nazism had the genocide of millions at it's core.
Sorry Fred – that really is a whitewashing of history isn't it?
From the red terror through to the Russian Famine, the collectivisation of farms and the great purges, the Soviet union was founded upon the political, economic and ideological repression of the people – you cannot disassociate this from the machinery of the imposition of communism on a people any more than you can separate the Nazi party from its own horrific crimes. The same applies to the Entire nations, ethnic groups and religious communities that were subjected to enforced relocation and imprisonment in Gulags in the name of "the people" under Communist rule – Both Communist and Nazi systems deemed a part of humanity unworthy of existence, in the Nazis case it was the Jews, in the Communists case it was the Kulaks, the Tartars, the Chechens and the Inguish – whilst apologists might like to claim that it was class based, the fact that the classes selected often fell into identifiable racial groups cannot be conceived as mere coincidence, any more so than we identify a religious identity as an identifiable racial group in the case of the Jews. These were the communities who had been oppressed and subjected to so many privations already that their status as untermensch was already secured. Engels himself referred to Slavs "national refuse" and claimed that they deserved to perish in the revolutionary storm.
The communist system in Russia could not have operated without the oppression and murder of identifiable groups any more so than the Nazis.
Then we look at China – with the murder, oppression and genocide of the cultural revolution, Cambodia and the subsequent ethnic cleansing of the Vietnamese, Chinese and Cham Muslims, half of the of the estimated 425,000 Chinese living in Cambodia in 1975 perished.
Communist ideology is as founded in the field of oppression and genocide as any form of Nazism, you cannot remove the ideology from the imposition of the policies any more so than you can with Germany!
