You refer to Wikipedia and say that the Holodomor was widely accepted as a result of Stalin's policies. But it was accepted by capitalists to fool people. To scare people who don't know the truth. To move the conversation about communism from an economic and class issue to the accusation of genocide. I'd better refer to the excellent collection of documents, The Hunger in the USSR 1929-1934:
The documents are in Russian, but you can use the translator:
Here we see that the dissidents disrupted the food harvest in 1932. By winter, the government deploys an active struggle against sabotage, theft, speculation, and withholding of food. When the famine begins, the Union government takes the problem under special control and begins to actively, centrally assist the affected areas. The main causes of the famine in 1932-1933 were: disruption of harvest, crop failure and bad weather. The most effective during the famine were the collective farms. Centralized distribution minimized the number of deaths from starvation.
So Stalin's policy saved people from the famine, which was caused by those who wanted to overthrow Stalin and bring back capitalism. Therefore, you are making a vain mistake when you blame Stalin and communists for the Holodomor. Think about it. Why did Stalin need to cause a famine?
Various criminals, not just political criminals, were imprisoned in the Gulag system. The criminals were paid a wage for their labor. When their sentence ended, they went free with money, profession, and most of them were successfully incorporated into Soviet society. And you call it genocide.
I wrote "Certainly many mistakes were made". How did you turn that into "a few mistakes"? And, of course, only idiots would undertake industrialization. Only idiots would think to develop their country's economy. So it is.
