Reading the supporting data behind the video all he's refuting is that it was a conscious genocide. But I don't think most think of the period as genocide, more as a failure of the economic system. Of planned economy. Much in the same way as the famine under Mao Zedong in China.
From one of the research papers linked in the video
"[..] indicate that the famine was real, the result of a failure of economic policy, of the "revolution from above" "
I really can't understand the fascination with Soviet and early communist China. I have very little issue with socialism and Marx & Engels had a lot of interesting ideas but to go from there to idolizing Soviet and China is to me baffling. Cuba I can sort of understand at least.
I mean it’s something that was declassified 50 years after it mattered. It’s not contemporary public messaging but private classified information withheld during the time it was most relevant.
The purges weren't just stalin going around shooting his opposition, they were a series of anti-corruption trials aimed at removing revisionists in power who were intent on seeing a return of capitalism. It was only in the worst cases, people who had deliberately committed espionage or sabotage, who were sentenced to death. Everyone else however, was largely either just barred from political life, or sent to jail, or not prosecuted at all as they hadn't done anything yet.
The return of capitalism? Lmao. There was no danger of 'returning' to something they never left. Read literally anything written by Lenin on the NEP. Stalin was literally the revisionist and needed to get rid of all the people who were still loyal to the international revolution or refused to kiss his ass and toe his line. Most of the people given show trials and purged were heroes from the civil war, Lenin's old friends and principled internationalist communists who didn't buy Stalin's BS theories- hundreds of them didn't suddenly turn traitor. Stop getting all your info from Hexbear, Lemmygrad and other meme cesspits and go actually read Marx and Lenin.
