The criticism of communism isn't that it has an explicit racial component that wants to kill racial minorities. It's that it has an ill-founded economic and psychological component that has the effect of killing lots of people.

When the Russian communists forcibly confiscated Ukrainian farm land and then tried to have them run by government commissars in one big mass farm system, they were doing it with the good intentions by trying to use use economies of scale to provide more food for everyone.

The problem was they robbed the actual farmers of agency and destroyed the actual motivation to efficiently grow food. Government employees, who get compensated whether they grow little food or a lot of food, are going to naturally maximize their personal gain. Since that gain couldn't be monetary, all they could do was minimize their own expense and effort. So they spent as little effort as possible, and those farms largely failed.

That lead to famine and mass starvation that was so bad, when the Nazis invaded Ukraine during WWII, some Ukrainians temporarily welcomed them as liberators.

That's why most of the modern day governments that still call themselves communist or socialist have largely abandoned the economic ideals of communism and have almost all adopted free market systems.
